06Sourced 2025-2026 signals
What's new at Vanta (2025-2026, sourced)
These sourced updates were researched on 2026-07-05 and are listed separately from the live comparison table so existing profile claims remain unchanged.
Vanta raised a $150M Series D in July 2025 led by Wellington Management at a $4.15B valuation (up from $2.45B a year earlier), with estimated ARR of about $220M (up from $100M in January 2024), serving over 12,000 customers with 1,000+ employees. This is a vendor/press-reported figure, not independently audited.
Alongside the Series D, Vanta made its first disclosed acquisition, buying Israel-based startup Riskey (undisclosed sum, July 2025) to add AI-driven continuous risk-monitoring capability, as CEO Christina Cacioppo signalled a push toward becoming a multi-product platform.
Vanta introduced an 'Agentic Trust Platform' (marketed as AI Agent 2.0) in late 2025/early 2026, adding autonomous policy drafting mapped to control gaps, AI-generated responses to inbound security questionnaires, automated vendor-risk evidence collection/scoring, and a 'Risk Graph' that visualises control dependencies -- a substantive product expansion beyond the automated-evidence-collection description currently on file.
Gartner Peer Insights lists Vanta at 4.4/5 from 278 reviews -- an independent review source not currently cited on the comparison page (which cites only Capterra and G2).
G2's own review page currently shows Vanta at 4.6/5 from about 2,424 reviews (Q2 2026) -- essentially unchanged from the 2,458-review figure already on file -- and G2 lists Vanta among its 2026 Best Software Awards winners in the Governance, Risk & Compliance category (a vendor-reported claim of '#1 in Security Compliance for 14 consecutive quarters through Spring 2026' should be treated as Vanta-sourced pending direct G2 confirmation).
In May-June 2025, Vanta disclosed (and published its own root-cause analysis for) a product code-change bug that exposed a subset of customer data -- employee names/roles and security-tool configuration metadata (not credentials, financial or health data) -- across tenants, affecting under 4% of its then ~10,000+ customers; the issue was found May 26 and remediated by June 4, 2025. This is factual, dated context relevant to a platform whose core positioning is 'trust management,' not currently reflected anywhere in the comparison page.
07Sourced 2025-2026 signals
What's new at BigID (2025-2026, sourced)
These sourced updates were researched on 2026-07-05 and are listed separately from the live comparison table so existing profile claims remain unchanged.
BigID achieved FedRAMP Authorized status in March 2026 through a partnership with Knox Systems, extending its platform to U.S. federal, defense and intelligence agencies; BigID also states it supports NIST SP 800-53, CMMC, FISMA, EO 14028, OMB guidance and the DoD Zero Trust Framework. This is not among the certifications currently listed in the FAQ (SOC 2 Type 2, ISO 27001, SOC 3, PCI DSS, FIPS 140-2, CSA STAR).
BigID was named a Leader in The Forrester Wave: Privacy Management Software, Q4 2025 (published December 2, 2025), with BigID stating it achieved the highest score of all vendors evaluated across 19 criteria and that reviewers cited 'best-in-class capabilities in personal data discovery, dynamic privacy risk assessment, and AI risk assessment.' This is a more specific, dated analyst credential than the general 'Forrester Leader in data discovery' reference currently in the profile.
BigID relaunched its core product as 'BigID Next' on February 24, 2025, describing it (in vendor marketing language) as its 'next-gen AI-powered' data security, compliance and privacy platform with a modular architecture, prompt-based classification and agentic AI assistants. Any future copy referencing 'BigID' as a single monolithic product name should account for this rebrand/relaunch to BigID Next.
BigID acquired Argentine cookie-consent startup illow (announced January 31, 2025) and used it to launch 'BigID CMP Express' on November 18, 2025 - a standalone, self-service cookie/consent management product with a 2-minute signup, AI-powered cookie classification, Global Privacy Control (GPC) support, and (per vendor marketing) 'transparent pricing without vendor lock-in.' This gives concrete, sourced evidence behind the existing table's 'Cookie/tracker scanning: Y' entry for BigID.
On March 30, 2026, BigID announced a unified privacy management capability combining personal data discovery, data-rights/DSAR automation, consent enforcement and AI privacy governance in one system, with vendor marketing claiming automation of workflows across '100+ regulations' including GDPR and CPRA; CEO Dimitri Sirota was quoted framing the shift as 'Privacy used to be about policy. Now it has to be about data.' This is a positioning statement worth noting if BigID's data-centric (versus workflow-centric) privacy pitch is referenced.
08Overlap and gaps
Vanta vs BigID: what the public data actually shows
Feature count is only a starting point. A customer should separate shared coverage from unique public signals, then test whether the vendor can run the required workflow end to end.
| Decision point | Public signal | Buyer interpretation |
|---|---|---|
| Shared evidenced coverage | DPIA/PIA assessments; RoPA / Article 30; Data mapping; Vendor risk; Privacy risk; AI governance; Approval workflows; plus 4 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only Vanta publicly confirmed | Policy/notice management; Training module; Spreadsheet import | Keep Vanta on the shortlist for these requirements, but ask BigID whether the same capability exists in current product scope. |
| Only BigID publicly confirmed | DSAR / privacy rights; Consent management; Cookie/tracker scanning; Retention management | Keep BigID on the shortlist for these requirements, but ask Vanta whether the same capability exists in current product scope. |
| Acompli reference column | No Acompli-only edge against both vendors appears in the tracked rows. | Use this as a third reference point where a narrower evidence-first privacy workflow may be preferable to a broader platform. |

11Customer due diligence
Questions customers should ask before choosing Vanta or BigID
A useful comparison should move beyond a product page checklist. Customers should ask each supplier to prove the same live workflow, with the same assumptions, so the difference between platform breadth and usable evidence becomes visible.
Run one real workflow
Ask Vanta and BigID to process the same example: new activity, assessment, RoPA update, supplier evidence, risk record, review and export.
Check evidence provenance
Confirm whether each important field in Vanta and BigID has a source, owner, review date and change history, not just a completed form.
Validate exports
Ask both vendors for a regulator-readable export for one legal entity, including controller and processor records where relevant.
Confirm commercial scope
Verify which modules, integrations, service hours, data residency options and support commitments are included in the quoted Vanta or BigID package.
12Shortlisting notes
Choosing between Vanta and BigID
Assess Vanta and BigID against the workflow you actually need to run - RoPA, DPIA, vendor and risk records - and how defensibly each exports its evidence.
- Shortlist Vanta when security compliance, SOC 2 or ISO evidence, GRC and trust operations are the centre of the buying case.
- Shortlist BigID when data discovery, classification and data security at scale across a complex data estate are the central requirement.
- Put the same case to Vanta and BigID: take one processing activity through its assessment, the RoPA update, supplier evidence, the privacy risk and a defensible export, and watch where each needs manual work.
13Ireland & UK
Vanta vs BigID: Article 30 records for Irish and UK teams
Both Vanta and BigID are weighed by Irish and UK privacy teams against the same fixed obligation: a record of processing activities under GDPR Article 30 - a controller record under Article 30(1) and a separate processor record under Article 30(2). In Ireland the Data Protection Commission (DPC) publishes Article 30 guidance; in the UK the ICO sets out what UK GDPR requires.
Whichever of Vanta or BigID an Irish or UK team weighs, the questions are the same: how deep is the Article 30 record, is EU and UK GDPR distinguished on one register, and can each legal entity produce a self-contained export its own supervisory authority can read?
| Article 30 check | Vanta | BigID | Why customers care |
|---|---|---|---|
| Controller record | Ask Vanta to show the Article 30(1) controller fields for one processing activity, including purposes, categories, recipients, transfers, retention and security measures. | Ask BigID to show the Article 30(1) controller fields for one processing activity, including purposes, categories, recipients, transfers, retention and security measures. | A controller record must stand on its own when a regulator or auditor asks for it. |
| Processor record | Ask Vanta to show Article 30(2) processor records separately from controller records, scoped to the controller on whose behalf processing is carried out. | Ask BigID to show Article 30(2) processor records separately from controller records, scoped to the controller on whose behalf processing is carried out. | Many tools capture controller records more clearly than processor records; customers should verify both. |
| Ireland and UK fit | Ask Vanta how EU GDPR and UK GDPR records are separated or tagged for Irish and UK entities. | Ask BigID how EU GDPR and UK GDPR records are separated or tagged for Irish and UK entities. | Irish DPC and UK ICO expectations are close, but entity scope, local law references and export format still matter. |
| Standalone export | Ask Vanta for a complete export that a legal entity could provide without giving the regulator product access. | Ask BigID for a complete export that a legal entity could provide without giving the regulator product access. | A defensible record should be readable outside the platform, with enough context to explain the processing activity. |
- Article 30(1) and 30(2) - does each of Vanta and BigID model controller and processor records separately, scoped by legal entity?
- DPC (Ireland) and ICO (UK) - is EU and UK GDPR distinguished on one register for Vanta or BigID?
- Export - can Vanta or BigID let each legal entity produce a self-contained record its own supervisory authority can read?
