Growing tired of OneTrust? Let's break you free
Ketch makes consent banner set-up a breeze with drag-and-drop tools that match your brand perfectly. Let us show you.
DataGrail built its platform around DSR automation and added consent management later, and the architecture still shows it. Consent lives in a browser cookie keyed to a device and versioned to the banner configuration, not to a person, so a routine banner edit wipes every stored opt-out. A Do Not Sell request only sets a cookie on a hosted subdomain and opens a support ticket, it never updates the CMP or reaches a downstream system. Ketch stores consent as a server-side permit tied to identity, so opt-outs survive banner edits, follow a person across every device, and propagate automatically to every connected system.
DataGrail started as a data subject request (DSR) company. Request Manager, the tool that connects to a company's SaaS stack and automates access and deletion requests, is still the product the rest of the platform is built around. Consent management came later, bolted onto that foundation rather than built alongside it. That sequencing shows up in the architecture: DataGrail is a DSR-first company doing consent, not a consent-first company doing DSR.
Three decisions define what that means in practice. The consent script deploys via Google Tag Manager within an async container, so it can load after adtech tags have already fired. Consent preferences live in a browser cookie keyed to a device ID that DataGrail generates and versions against the published banner configuration, not to a person. And DSR and Consent are separate products that share a platform but not an identity layer, an event bus, or any native connection between them.
Ketch was built the other way. Consent is a permit tied to identity, stored server-side, and orchestrated across every connected system the moment a person makes a choice. The gaps below are not cosmetic. They are the direct result of DataGrail's architecture, and each one maps to a discovery question you can ask before Ketch ever comes up.

Key takeaway: DataGrail's consent cookie stores a person's consent choice alongside a reference to the banner's configuration version. Publish a new configuration, even to fix a typo, and every stored consent record is treated as stale and wiped.
DataGrail's consent architecture ties a person's choice to two things: a device-generated cookie and the version of the banner configuration in place when that choice was made. When a company publishes a new configuration, whether it is a real policy change or a copy fix, the configuration version changes, and the browser cookie's reference goes stale. DataGrail cannot tell a material change from a typo, so it invalidates every consent record built against the old version.
The practical result is that a consumer who opted out last month is opted back in, silently, the next time the company edits the banner. Nothing tells consumers their preferences have reset. They only find out if they notice the banner reappearing or if they check whether a "Do Not Sell" choice is still being honored.
Regulators have already drawn a bright line on this exact failure mode. The CPPA fined Todd Snyder $345,000 for an opt-out mechanism that failed to process consumer preferences due to misconfiguration and excessive verification demands and made clear that deploying a consent management platform does not absolve a business of responsibility if opt-out choices are not consistently honored. A platform that resets consent on every routine publish turns that exposure into a recurring event rather than a one-time misconfiguration.
What this means for DataGrail customers:
The Ketch difference: Ketch stores a consent choice as a permit, tied to a person's identity and decoupled from any banner or configuration version, in its Permission Vault. Editing copy, adding a vendor, or updating a banner never touches an existing permit. A person's opt-out survives every publish because it was never stored against the publish in the first place.
Ask DataGrail: When your team updates the banner, even to fix copy, what happens to users who already opted out? Do their preferences carry over or reset?
Key takeaway: DataGrail's consent script has no read path to any server-side preference store. Every read is a parse of the local browser cookie, so a consent choice exists in exactly one browser on one device. Ketch resolves consent to a person's identity, so a choice made once applies everywhere that person shows up.
Privacy laws grant rights to consumers, not to browsers. A person who opts out on their phone reasonably expects that choice to hold when they open the same site on their laptop, and regulators evaluating whether an opt-out was honored are asking about the person, not the device. Cross-device consent is only possible if the platform stores the choice somewhere all devices can reach and ties it to something that identifies the person.
We analyzed the consent bundle DataGrail serves on live deployments, and the architecture rules this out. The function that retrieves a visitor's choices, getConsentPreferences(), reads and parses the local datagrail_consent_preferences cookie and nothing else, and across every network call the bundle makes, there is no read path that pulls stored preferences back from a server.
The preference is written to one browser's cookie and read from that same cookie, so it is born, lives, and expires on a single device. The same analysis confirmed the reset mechanism behind the banner-edit problem covered above: when the published configuration's version UUID differs from the one in the visitor's cookie, the preference cookie is deleted, the version is bumped, and the visitor is treated as un-consented and shown the banner with policy defaults.
What this means for DataGrail customers:
The Ketch difference: Ketch stores consent as a server-side permit in the Permission Vault, resolved to a person through Ketch Identity Management rather than pinned to a cookie.
When the same person is recognized on another device or browser, through a login, a known identifier, or configured identity resolution, the existing permit applies, so one choice governs every surface where that person appears, and clearing a cookie never erases what they decided.
Ask DataGrail: When a consumer opts out on their phone, what carries that choice to their laptop? And does your consent script make any server call to retrieve stored preferences, or is every read from the local cookie?
Key takeaway: In DataGrail's recommended deployment, consent.js is delivered as a tag inside your GTM container, so the consent layer cannot exist until GTM does. In the EU, this creates a circular dependency that DataGrail can only solve by handing script delivery back to engineering.
DataGrail documents two ways to get consent.js onto a site: through the Google Tag Manager integration, which it recommends for most websites, or as an embedded script a developer places in the page <head>. In the recommended path, publishing from DataGrail creates a consent banner tag in your GTM container, so the consent script loads as part of GTM rather than ahead of it. Anything that executes before the container initializes, from inline scripts to hardcoded pixels, runs before the consent layer exists on the page.
This becomes a structural problem in the EU, where a 2025 German court ruling established that GTM itself needs consent before it loads. A consent script that lives inside GTM to deliver consent, while GTM needs consent to deliver that script, creates a circular dependency. The workaround DataGrail documents is the embedded deployment, which moves script delivery onto a developer-placed, engineering-maintained snippet, the exact dependency a consent platform is supposed to remove.
What this means for DataGrail customers:
The Ketch difference: Ketch loads the page <head> before GTM or any tag manager initializes, so consent is established before any tag has a chance to fire, and there is no circular dependency to engineer around in any jurisdiction.
Ask DataGrail: Your consent script is deployed as a tag within our GTM container. What gates the scripts and pixels that execute before GTM initializes? And for our EU properties, if GTM itself needs consent before it loads, how does your banner load?
Key takeaway: DataGrail enforces consent by blocking a script from firing again. It has no mechanism to reach into a downstream system and retroactively suppress a person whose data was already synced there before the decline.
There are two different ways a consent platform can enforce a "no": it can stop a script from firing the next time the page loads, or it can reach into every system that already has that person's data and instruct it to stop processing that person going forward. The first is Type 1 enforcement. The second, server-to-server suppression that changes behavior inside advertising platforms, analytics tools, and data warehouses, is Type 2. DataGrail only does the first.
In practice, that means a consumer who declines a marketing cookie on Monday can still be part of a Facebook Custom Audience or an analytics cohort that was built from data collected before Monday, because nothing in DataGrail's architecture tells Facebook or the analytics platform to drop that person. The opt-out changes what happens on future page loads. It does not retroactively change what those downstream systems do with the record they already have.
Regulators have not treated "we stopped the script" as sufficient on its own. Enforcement actions consistently test whether a business can show that a consumer's choice changed behavior everywhere their data lives, not just on the page where the choice was made.
What this means for DataGrail customers:
The Ketch difference: Ketch enforces consent with Type 2, server-to-server orchestration. The moment a person's choice changes, Ketch calls out to every connected downstream system (ad platforms, CDPs, warehouses, internal databases) and instructs each one to suppress that specific person, not just to stop a script from firing on the page.
Ask DataGrail: If a consumer's data already reached Facebook or a data warehouse before they opted out, what happens to that record? Does anything tell that system to stop using it?

Key takeaway: DataGrail's DSR handling is a fixed, linear pipeline: intake, verification, processing, completion. Teams can adjust automation levels and insert checkpoints, but cannot restructure the flow, and opt-out requests run in a separate queue from access and deletion requests entirely.
DataGrail's Request Manager moves every request through the same four phases in the same order. Privacy teams can turn automation up or down at each phase and add tasks or conditional checkpoints, but the underlying sequence cannot be re-architected around how the business actually operates. Do Not Sell and other opt-out requests run in a queue separate from access and deletion requests, rather than within the same configurable process.
That rigidity becomes a real constraint the moment request volume or complexity grows. A request that should be routed differently based on identity confidence, product line, or jurisdiction has nowhere to go within a fixed pipeline except through a manual exception.
What this means for DataGrail customers:
The Ketch difference: Ketch treats DSR handling as a free-form, editable workflow canvas rather than a fixed pipeline: parallel branches, decision gateways, and granular building blocks like Review & Redact, Set Permits, Identity Verification, and direct system queries through Transponder, all inside a single configurable process.
A Do Not Sell request runs through Set Permit and Type 2 orchestration within the same workflow, not in a separate queue.
Ask DataGrail: Can I route a request differently based on identity confidence or jurisdiction, or does every request move through the same four phases regardless of type?
Key takeaway: A Do Not Sell request in DataGrail sets a device cookie that handles suppression in that one browser, while the downstream signal to ad platforms and CDPs waits for email verification. Nothing in the flow is tied to a person, so the opt-out doesn't follow them anywhere.
When a consumer submits a Do Not Sell request through DataGrail's Privacy Request Center, DataGrail immediately sets a ccpa_dnsmpi cookie in that browser, and DataGrail Consent can be configured to respond to that signal by adjusting which tracking categories stay enabled on the site. That coupling is real, but look at what it's made of: a cookie in one browser on one device, plus a policy setting that, as DataGrail's docs note, may need to be enabled before the signal is handled at all.
Opt out on a phone, and the laptop is untouched, clear cookies, and the signal is gone, and whether the person's consent record in the audit log is ever updated, as opposed to the signal simply being honored at page load, is not something the documentation specifies.
The downstream half of the flow has a different problem. DataGrail does offer opt-out integrations with systems like Facebook Marketing, Braze, and Segment, but those integrations only initiate once the request reaches In Progress. This requires the consumer to verify their email unless verification is switched off in settings, and an unverified request will auto-cancel after 7 days.
The CPPA's $632,000 settlement with Honda, an automotive company, established that opt-out processes requiring more steps than the law allows are themselves a violation. A flow where the on-site cookie is immediate, but the downstream signal waits on an email verification, the regulations say you cannot demand of an opt-out, is exactly that shape.
What this means for DataGrail customers:
The Ketch difference: In Ketch, a Do Not Sell request runs through Data Subject Rights Automation, which is natively coupled to the same Permission Vault that powers Consent Management. Submitting the request updates the person's consent record and triggers server-to-server orchestration to every connected downstream system in a single action, with no verification step gating the opt-out. Because the permit is tied to identity rather than a cookie, the choice follows the person across every device and browser.
Ask DataGrail: If I opt out on my phone, am I opted out on my laptop? And before your integrations signal Facebook or Segment, what has to happen first, and what happens to the request if I never verify my email?
Key takeaway: DataGrail's DSR automation is keyed on email, but most of the systems in a modern martech and adtech stack recognize a person by a device ID, a hashed identifier, or a system-generated UUID, not an email address.
Email is DataGrail's default and, in most implementations, only identifier for rights automation. That works for systems that store an email address as the primary key. It breaks down everywhere else:
Reaching any system on that list requires either a custom integration a customer builds and maintains, or manual entry by an admin. DataGrail's widely cited "2,400 integrations" figure blends three very different things: fully automated API connections, "Internal" integrations that the customer has to build and deploy themselves, and "Direct Contact" integrations that are, in practice, a templated email sent to a human at the vendor.
A meaningful share of that headline number is the third category, and even the automated API integrations can take up to two weeks to complete.
What this means for DataGrail customers:
The Ketch difference: Ketch collects every relevant identifier (Amplitude's deviceID, Segment's anonymous_id, the AMCV cookie, and more) directly on the page at the moment of consent, through configuration rather than engineering. When a rights request runs, Ketch orchestrates downstream using each system's own native identifier through pre-built, identity-aware integrations, so a Do Not Sell reaches Amplitude and Segment the same way it reaches a CRM keyed on email.
Ask DataGrail: Of your 2,400 integrations, how many are fully automated API connections versus a Direct Contact email to a human at the vendor?

Key takeaway: DataGrail's has no way to inspect the actual network payload a tracking pixel sends, which is exactly where CIPA and VPPA exposure originates.
DataGrail's Responsible Data Discovery scans internal databases and samples up to 20,000 records from a limited set of supported SaaS applications through API calls. That approach can classify structured data at rest, but it is architecturally blind to what happens on the client side: the actual data packet a pixel sends when a page loads, when a form is submitted, or when a video plays. DataGrail's Privacy Inspector, a browser extension, is a manual tool someone has to run; it is not a continuous, automated capability.
That distinction matters because the current wave of CIPA and VPPA demand letters and litigation is built almost entirely on client-side evidence: a pixel that sent video-watch data without a consent gate, or sensitive health or financial data that reached an advertiser before an opt-out was honored. The California AG's $1.55 million settlement with Healthline Media turned on exactly this pattern: sensitive browsing data shared with advertisers without valid consent. A discovery tool that only sees structured records in supported SaaS apps cannot detect a pixel payload leaving the browser because that payload was never within the systems it scans in the first place.
What this means for DataGrail customers:
The Ketch difference: Data Sentry inspects the actual network traffic leaving a page in real time across web, mobile, and CTV, not just the structured records within supported SaaS apps. It classifies the attributes in a payload, checks whether the sending system is authorized, and flags CIPA and VPPA patterns, such as health, financial, or video-watch data crossing to a pixel without a consent gate. The Ketch Insights engine, part of the Ketch Agent Network, also reads vendor DPAs and contracts and continuously compares their terms to the live configuration, flagging an issue the moment documentation and practice diverge.
The gap extends to cookie scanning itself. DataGrail's scanner sees first-party cookies and storage only, so it cannot block a third-party cookie even after it identifies one. Ketch runs an emulator-based scan built to catch third-party trackers that an SDK-telemetry-only approach misses entirely.
Ask DataGrail: For a tag like the Facebook Pixel, how do you discover what data attributes are in the payload? Do you inspect the actual network request leaving the browser? And can your scanner block a third-party cookie, or only see it?
Key takeaway: DataGrail's documentation, product pages, and feature list do not mention marketing preferences. Regulatory consent and subscription-level marketing preferences are two different legal requirements, and DataGrail only addresses one of them.
CAN-SPAM, TCPA, and their state equivalents require a business to demonstrate auditable suppression of marketing communications at the subscription-topic and contact-method level, separate from, and in addition to, regulatory consent for data sale or sharing. DataGrail's product line does not include a marketing preference module of any kind.
Ketch ships Marketing Preference Management as a licensed module alongside Consent and Rights: configurable subscription topics across email, SMS, mail, and phone; orchestration into Braze, Marketo, Iterable, and Salesforce Marketing Cloud; global opt-out controls; a preference dashboard with subscription insights; CSV import and export; and zero-party progressive profiling with native Salesforce, Segment, and Braze integrations. Consent, rights, and subscriptions all show up in one preference center rather than three disconnected surfaces.
If marketing preferences are part of the evaluation, DataGrail simply has no product to compare.
Key takeaway: DataGrail's mobile support is a JavaScript callback rendered inside a WebView. There is no native iOS or Android SDK, and no documented capability for connected TV at all.
Consent management built for the browser doesn't automatically extend to a native app or a television screen. DataGrail's mobile story is a JavaScript callback intended for WebView contexts: there's no native Swift or Kotlin package, no App Tracking Transparency handling, and no documented way to show or enforce consent in a native app without a browser context. Connected TV (Roku, Apple TV, and similar platforms) has no documented capability.
As engagement continues shifting into native apps and CTV advertising, a browser-only consent model leaves those surfaces effectively ungoverned. A company running a native app or a CTV ad campaign on DataGrail has no first-party way to capture or enforce a privacy choice there.
What this means for DataGrail customers:
The Ketch difference: Ketch ships native iOS, Android, React Native, Flutter, and Ionic SDKs, and CTV consent is already live in production at Fox and Paramount through QR-code flows, a headless API, and companion-device authentication.
Ask DataGrail: Can you show consent in a native iOS app, an actual Swift app with no browser context? On Roku or Apple TV, how does a consent banner even appear?
Key takeaway: DataGrail's AI capability is limited to AI-assisted DSR handling and assessment autofill. It has no product that governs whether data can be used inside an AI model or enforces consent at the point of an LLM interaction.
DataGrail's AI investment is focused on making its existing DSR and assessment workflows faster: suggesting answers, summarizing documents. None of that touches the separate question of what happens once data reaches an AI system: whether a model was trained on data a person opted out of, or whether a live LLM query pulls in information it shouldn't have access to. DataGrail has no documented product in this space.
Ketch AI Sentry closes that gap directly. It continuously monitors for unapproved data flows and risky queries, enforces consent and rights signals at the moment of every LLM interaction, and logs every AI action so a privacy team can demonstrate governance rather than reconstruct it after the fact.
If governing what data is allowed into an AI model, not just automating requests about it, is part of the evaluation, DataGrail has nothing built for that layer.
Key takeaway: DataGrail's DPIA and PIA autofill is in beta and still walks a person through questions one at a time. Once an assessment is filed, nothing monitors whether the answers stay accurate as systems and policies change.
Both platforms offer DPIA and PIA templates, risk registers, and some form of AI-assisted population, so the surface comparison looks close. The difference shows up in what happens after an assessment is filed. DataGrail's AI-powered assessment autofill remains in beta: it can suggest an answer from existing system information, but a person still moves through the assessment question by question.
Template import and cascading assessments (where one answer, like a flag for sensitive health data, automatically triggers a related assessment) are not documented capabilities. Once an assessment is completed, DataGrail does not continue checking whether the underlying answers remain true.
That last gap matters more than it sounds. A completed DPIA that says data is retained for six months is only useful if something notices when the actual system configuration drifts to indefinite retention.
The Ketch difference: Ketch pre-populates an assessment the moment it's created, pulling from prior answers, uploaded DPAs, and existing system inventory, so most assessments start largely complete rather than blank.
Trigger rules can cascade (a flag for sensitive health data can auto-initiate a related DPIA) and on completion, the Ketch Agent Network cross-references the answers against regulatory requirements and opens an Insight for any gap, linked to the specific system and assessment. Findings keep feeding that Insights layer for ongoing monitoring, so an assessment doesn't go stale the day it's filed.
Key takeaway: DataGrail's consent and rights products keep separate logs with no shared identity. To prove an individual's consent, DataGrail recommends the consumer retrieve their own browser cookie, and because no server-to-server orchestration exists, there is no record of whether an opt-out actually reached a downstream system.
Proof breaks down at three different levels in DataGrail. At the aggregate level, consent reporting is a monthly CSV download, one row per device UUID, with no dashboard, no trend view, and no breakdown by jurisdiction or purpose. DSR reporting lives in a separate queue view with its own CSV export, and the two cannot be joined on a person, since neither system shares an identity with the other.
At the individual level, proving a specific person's consent gets stranger. DataGrail's own guidance is to ask the consumer to open their browser, locate the datagrail_consent_id cookie, and send the value back. What that record shows is a device timestamp: not the experience the person saw, the jurisdiction they were in, the method they used, or anything about what happened downstream.
At the orchestration level, there's simply nothing to show. If a regulator or a plaintiff's attorney asks whether a specific person's opt-out reached Facebook or Amplitude, DataGrail has no log of that event, because no server-to-server call was ever made in the first place. A platform can't produce a record of an action it never took.
What this means for DataGrail customers:
The Ketch difference: The Ketch Permit Statistics dashboard refreshes every eight hours with global trends, allowance rates by jurisdiction and purpose, and user distribution by identifier. The Ketch Audit Log is queryable by any identifier (email, phone, or any system ID) and returns consent per purpose with timestamp, jurisdiction, property, the exact interaction method from 24 enumerated options, GPC status, and the legal-basis default. For every downstream system, the log shows which identifier was sent, whether the call succeeded, and, if it didn't, why. One query returns consent, rights, and subscriptions for a single person, in one place.
Ask DataGrail: If a consumer says their opt-out wasn't honored and a regulator asks for proof, how do I look that up, what do I search by, and what does the record show? Can you show the record of a specific user's opt-out reaching Facebook: the API call, the identifier, and the result?
Key takeaway: Both platforms have AI. DataGrail's Vera is a chat assistant that a person has to prompt, with an MCP server that mostly reads data. The Ketch Agent Network runs continuously, executes approved changes, and serves as the platform's control plane.
DataGrail's Vera is an AI assistant: a chat interface with embedded suggest-and-accept actions and MCP access. A person has to invoke it. Vera's MCP tools search DSR tickets, check integration status, read the risk register, and query consent, a reporting layer that is disabled by default, with any write tools gated separately behind that.
The Ketch Agent Network is an orchestration layer that reasons across three data domains at once: legal obligations like global privacy laws and enforcement actions, documented policies like DPAs and privacy policies, and operational reality like live Ketch configurations and data repositories. It runs continuously across every product in the platform. When it finds a gap between what a company is required to do, what it says it does, and what its systems actually do, it surfaces that gap as a prioritized Insight and, with approval, executes the fix directly. The Ketch MCP server is a control plane over the full API: an agent can update consent, trigger a workflow, manage identifiers, and drive orchestration.
The distinction is who starts the work and whether it finishes. Vera suggests when a person asks. The Agent Network monitors on its own and acts when approved.
Key takeaway: The gap between DataGrail and Ketch is architectural. DataGrail was built around DSR ticketing with consent added afterward. Ketch was built around identity-resolved consent that orchestrates across every connected system.
With DataGrail, a privacy program depends on a person noticing when a banner edit resets consent, a GTM admin keeping triggers current, and engineering building the integrations DSR automation needs to reach non-email systems. With Ketch, those same outcomes are enforced automatically, by design, and are provable on demand.
Enforcement in 2026 is judged on outcomes, not on whether a banner was displayed. Regulators, including the CPPA (CalPrivacy) and multiple state attorneys general, have made clear, through settlements like Honda, Todd Snyder, and Healthline Media, that a business is responsible for whether an opt-out actually stops data use across every system that touches that person's data, regardless of what the vendor's documentation promises.
A consent architecture that resets on every banner publish, an opt-out that stops at a subdomain cookie, and a discovery tool that can't see a pixel payload leaving the browser are not edge cases. They are the specific failure modes regulators have already fined companies for. DataGrail's consent-as-an-afterthought architecture makes each of them a structural risk rather than a one-time configuration mistake.
Ketch was built for person-level intent, real-time orchestration across every connected system, and provable outcomes from day one. Switch to Ketch today.
