3 reasons why privacy teams switch from BigID to Ketch
First-generation data discovery platforms don't solve for modern-day requirements. Among the challenges: Ketch is a next-generation data discovery and classification platform: dynamic, secure, and natively integrated with our privacy management software to enable key privacy use cases like ROPAs, data mapping, and more.
Slow and cumbersome
Traditional data discovery and classification scanning methods like BigID are slow to gather information, sometimes taking months to catalog data.
Complex and costly implementation
Customers report costly software and long implementation cycles to get the tool working for their business's unique needs.
Lacking agility and speed to innovation
As privacy management providers get larger, their ability to make dynamic shifts according to customer demands grows slower. Forrester rated Ketch's privacy management innovation roadmap a 5/5, compared to 3/5 for BigID.
Why teams choose Ketch over BigID
Dynamic, always-on data discovery and classification
First-generation data discovery tools are incomplete and time-consuming, relying on manual surveys or recreating your information in a parallel data lake. With Ketch, data discovery is always-on, giving you a real-time view of information used across your business, including data in vendor and partner systems. Data stays where it is, with no doubling up in parallel categories or data lakes. The responsive classification engine applies labels so you understand what types of information you have.
Natively integrated with privacy management tools
Data discovery and privacy management aren't separate things. With Ketch, data discovery is natively integrated with the privacy management platform, enabling critical use cases like assessments, DSR fulfillment, reporting and audits, and centralized data governance policy-setting and enforcement.
Centralized control on decentralized data
With Ketch, data stays in your systems and infrastructure, but you set access and security policy from the Ketch services interface. Set and enforce policies on who accesses data and for what purpose, and set security parameters for how data appears on access: plain, masked, tokenized, encrypted, or statistically anonymized.
12x ROI with Ketch data discovery
Operational efficiency: Eliminating manual surveys drives 70% efficiency and operational cost savings. Reduced storage cost: Ketch data discovery can drive a 30% reduction in data surface area through redaction of stale and unused data, which for most companies costs $700k/petabyte/year. Enhanced risk profile: Reducing your data footprint and improving data hygiene reduces breach risk and lowers discovery cost in the event of a breach.
Feature comparison
BigID vs. Ketch, side by side
BigID is a deep data-intelligence suite. Ketch pairs always-on discovery with consent, rights, and Growth so privacy choices are enforceable — not just catalogued.
Discovery
| Area | Ketch | BigID |
|---|---|---|
| Data discovery | Always-on discovery and classification across systems at the attribute level, without moving data. | Strong ML-based discovery; customers report complex, resource-intensive implementation to get coverage live. |
| Time to insight | Streamlined deployment with automated workflows so teams see value without a long services project. | Implementation is often complex and costly, slowing time to a usable map. |
Permissioning
| Area | Ketch | BigID |
|---|---|---|
| Consent & rights | Consent orchestration, DSR automation, and Identity Sync in the same platform as discovery. | Privacy management exists in the suite, but programs often still assemble consent and rights elsewhere. |
| Usability | Intuitive UI built for privacy, marketing, and engineering to share — fast adoption without a steep learning curve. | Platform can be hard to navigate; teams report significant time and training to become productive. |
Growth
| Area | Ketch | BigID |
|---|---|---|
| Activation | Preference Management, Progressive Consent, and Profile Management turn permissioned data into AI-ready growth. | Discovery- and governance-led; Growth-layer activation is not the center of the product. |
