Ask which B2B data provider is the most privacy-compliant, and the honest answer isn’t as differentiated as most comparison content makes it sound. We checked four providers, Lusha, Apollo, ZoomInfo, and Cognism, against their actual published certifications, not marketing claims. Most of the core credentials are closer than a quick scan suggests. The real differentiator turned out to be something narrower and newer, readiness for AI agents having direct access to the data, not privacy in general.
TL;DR
- What it is: A comparison of B2B data providers on actual published compliance certifications, US and EU privacy law alignment, and readiness for AI-agent access specifically.
- Core privacy certifications are close to table stakes among three of the four: Lusha, ZoomInfo, and Cognism all hold ISO 27001, ISO 27701, and SOC 2 Type II. This isn’t a three-way differentiator, it’s the baseline for being taken seriously in this category.
- Apollo holds a narrower set: ISO 27001 and SOC 2 Type II, both audited by A-LIGN, plus stated CCPA and CPRA alignment. It does not publish ISO 27701, ISO 31700, or ISO 42001, the certifications specific to privacy information management and AI governance.
- Where Lusha actually differs: ISO 42001, the AI management systems standard, relevant specifically because AI agents now have direct, often unsupervised access to this data. Lusha is the only one of the four with the certification itself — ZoomInfo holds a related but distinct credential (see below).
How we evaluated
- Published, verifiable certifications, not general compliance language on a marketing page.
- US-specific privacy law alignment, CCPA and CPRA specifically — we did not find vendor-specific documentation on newer state laws (Virginia’s VCDPA, Colorado’s CPA, Connecticut’s CTDPA, Utah’s UCPA) for any of the four, so we’re not claiming alignment on those here.
- Do-Not-Call and suppression list practices, where documented.
- AI-specific governance, a newer category that most compliance comparisons don’t check for yet, and that matters more now that AI agents query this data directly. We separated “ISO 42001 certified” from “holds an AI-governance-related certification” since these aren’t the same claim.
Quick comparison
| Lusha | Apollo | ZoomInfo | Cognism | |
Verified against each vendor’s own trust center / compliance pages, current as of August 2026. Certifications lapse and renew — reconfirm before citing in sales or procurement conversations.
1. Lusha
Lusha holds the same core certification set as ZoomInfo and Cognism, ISO 27001, ISO 27701, and SOC 2 Type II, plus ISO 31700 for privacy by design and a TRUSTe seal, and its data practices are built to support customers’ GDPR and CCPA compliance needs. What sets it apart in this specific comparison is ISO 42001, the AI management systems standard, which none of the other three hold as a direct certification — ZoomInfo holds a related but distinct AI-governance credential (see its section below).
Verified-at-source data, rather than aggregated from third parties, is the other piece of Lusha’s compliance story worth naming here, it’s easier to stand behind a privacy claim about data you’ve verified yourself than data pulled together from providers you can’t fully vouch for.
Pros
- Full core certification set: ISO 27001, ISO 27701, SOC 2 Type II, ISO 31700, TRUSTe
- ISO 42001 certified, the only one of the four compared here with the certification itself
- Data verified at the source, not aggregated from third parties
- Data practices designed to support customers’ GDPR and CCPA compliance needs
Cons
- Total contact volume trails the largest providers in the category
- No published Do-Not-Call suppression-list scrubbing documentation, unlike Cognism
Best for
Teams that want the full core compliance set plus AI-specific governance, relevant now that agents, not just people, are the ones querying the data.
2. ZoomInfo
ZoomInfo holds the same core certification set as Lusha and Cognism, ISO 27001, ISO 27701, and SOC 2 Type II, along with TRUSTe-backed GDPR compliance and stated CCPA/CPRA alignment. This is a stronger compliance posture than ZoomInfo’s own marketing tends to lead with, its public narrative focuses more on data breadth and AI connector launches than on certifications, but the certifications are real and independently confirmed.
On the AI-governance question specifically, ZoomInfo does not hold ISO 42001 certification itself, but it does hold something adjacent worth naming precisely: on August 18, 2026, ZoomInfo announced its third consecutive TRUSTe Responsible AI Certification from TrustArc, tested against principles from the EU AI Act, the NIST AI Risk Management Framework, ISO 42001:2023, and the OECD AI Principles. That’s a governance certification informed by ISO 42001, not the ISO 42001 management-system certification itself, a real distinction worth being precise about rather than collapsing into “ZoomInfo has no AI governance credential.”
Pros
- Full core certification set: ISO 27001, ISO 27701, SOC 2 Type II, plus TRUSTe GDPR
- Third consecutive TRUSTe Responsible AI Certification, renewed August 2026, tested against ISO 42001 principles among others
- Largest published contact database in the category
Cons
- No ISO 42001 certification itself found published, only the related TRUSTe Responsible AI credential
- Enterprise-only pricing and contract terms
Best for
Enterprise teams that already have ZoomInfo as their primary provider and want confirmation the compliance posture is real, not just brand reputation.
3. Cognism
Cognism has positioned itself as “compliant-first” for years, and the certifications back that up: ISO 27001 since 2019, ISO 27701 since 2022, SOC 2 Type II, plus active Do-Not-Call and suppression list scrubbing across 15 major lists, and documented GDPR processes, legitimate interest assessments, data subject request handling, and 72-hour breach notification.
We found no published ISO 42001 or TRUSTe Responsible AI certification for Cognism. Its compliance strength is specifically EMEA-oriented, its Diamond Data phone verification and DNC compliance are strongest in UK and European markets, less differentiated for US-only data needs.
Pros
- Full core certification set: ISO 27001, ISO 27701, SOC 2 Type II
- Documented GDPR process depth, legitimate interest assessments, DSAR handling, breach notification timelines
- Do-Not-Call scrubbing across 15 major suppression lists — the most explicitly documented DNC practice of the four
Cons
- No ISO 42001 or related AI-governance certification found published
- Compliance strengths skew EMEA-specific, less differentiated for US-only needs
- No self-serve pricing, requires a sales conversation
Best for
Teams whose primary compliance concern is EMEA data handling specifically, where Cognism’s DNC and GDPR-process depth is strongest.
4. Apollo
Apollo holds a narrower certification set than Lusha, ZoomInfo, and Cognism, but it is not uncertified. Apollo publishes ISO 27001 certification and a SOC 2 Type II report, both audited by A-LIGN, through its own trust center, and states GDPR compliance as both a data processor and controller, alongside CCPA and CPRA alignment.
What Apollo does not publish, as of this review, is ISO 27701 (the privacy-management extension to ISO 27001), ISO 31700 (privacy by design), or any ISO 42001 or Responsible-AI-specific certification. That’s a real, specific gap relative to the other three, not an absence of any certification at all.
Pros
- ISO 27001 certified and SOC 2 Type II reported, both via A-LIGN
- Stated GDPR compliance as processor and controller, plus CCPA/CPRA alignment
- Large contact database and broad feature set outside of compliance specifically
Cons
- No published ISO 27701 (privacy management) or ISO 31700 (privacy by design) certification found
- No ISO 42001 or Responsible-AI-specific certification found published
- No EU/UK in-region data residency. EU, UK, and Swiss data is transferred to US-based datacenters under Standard Contractual Clauses and the EU-US Data Privacy Framework
Best for
Teams that want baseline, independently audited security certification (ISO 27001, SOC 2 Type II) without needing the privacy-management or AI-governance layer specifically.
What ISO 42001 actually covers when an agent, not a person, is pulling the data
Most compliance certifications were written for a person logging into a dashboard. ISO 42001 is different, it specifically governs risk assessment, oversight, and accountability for automated systems making or feeding decisions without a person reviewing each one. That’s the exact shape of what happens when a rep connects Claude or ChatGPT to Lusha through MCP.
Here’s what that actually looks like end to end:
A rep asks Claude, connected to Lusha through MCP, to find VPs of Marketing at companies showing a hiring surge in the last 30 days → Claude calls Lusha’s search and signals endpoints directly, no person checks each record before Claude sees it → the response comes back with a confidence score and a refresh date on every contact, and the signal that triggered the match → the rep reviews the shortlist Claude assembled, not a raw unverified pull.
Lusha’s ISO 42001:2023 certification (issued by RONET International Certification Services, effective May 18, 2026, certification no. AI5902) covers the development, sales, and support of the Lusha platform, its AI management system as a whole, not a line-item audit of any single API field. What it establishes is that the governance sits at the platform level: the same managed system handles a search or enrich call whether it’s triggered by a person in the app or by an agent through MCP, rather than the AI-connected pathway being carved out and governed separately, or not at all.
None of the other three providers compared here publish a certification covering that same scenario, an agent pulling data with no human review step in between. ZoomInfo’s TRUSTe Responsible AI Certification is the closest adjacent credential, but it’s a governance attestation tested against AI-risk frameworks, not a certified management system for the AI-adjacent data pipeline itself.
How to choose
Need a specific, auditable privacy-management certification for procurement?
Lusha, ZoomInfo, and Cognism all hold the same core set, ISO 27001, ISO 27701, SOC 2 Type II. Apollo holds ISO 27001 and SOC 2 Type II but not ISO 27701.
Your AI agents have direct access to the data, not just your team?
Lusha is the only one of the four with ISO 42001 certification itself. ZoomInfo holds a related TRUSTe Responsible AI Certification tested against ISO 42001 principles — worth asking about if you need the management-system certification specifically versus governance-adjacent credentialing.
Your compliance need is EMEA-specific, or DNC/suppression-list scrubbing matters most?
Cognism’s DNC and GDPR-process depth is the most built out for that region and requirement specifically.
Largest database and enterprise budget?
ZoomInfo holds the same core certifications with the biggest published dataset.
Baseline security certification without the privacy-management layer?
Apollo covers ISO 27001 and SOC 2 Type II.
FAQs
Is Lusha the only B2B data provider with ISO 27701?
No. ZoomInfo and Cognism both also hold ISO 27701. It’s closer to a baseline expectation among the more established providers than a differentiator on its own.
Does Apollo have any published compliance certification?
Yes. Apollo holds ISO 27001 certification and reports SOC 2 Type II compliance, both audited by A-LIGN, and states GDPR, CCPA, and CPRA alignment. What Apollo does not publish is ISO 27701, ISO 31700, or an AI-governance-specific certification like ISO 42001.
What is ISO 42001, and why does it matter for B2B data?
ISO 42001 is a management systems standard specifically for AI systems, distinct from privacy-focused standards like ISO 27701. It matters more now that AI agents query business data directly through connections like MCP, without a person reviewing each result. It is different from, though related to, credentials like TRUSTe’s Responsible AI Certification, which tests against ISO 42001 principles without being the ISO 42001 certification itself.
Does ZoomInfo have an AI governance certification?
ZoomInfo does not hold ISO 42001 certification itself, but it holds a TRUSTe Responsible AI Certification from TrustArc, renewed for the third consecutive year in August 2026, which is tested against principles from ISO 42001:2023, the EU AI Act, the NIST AI Risk Management Framework, and the OECD AI Principles.
Which provider is best for GDPR compliance specifically?
Cognism has the most documented GDPR process depth, legitimate interest assessments, data subject request handling, and 72-hour breach notification. Lusha and ZoomInfo both hold certifications, including ISO 27701 and TRUSTe, that support GDPR-aligned data handling.
Conclusion
Privacy certification isn’t the differentiator most comparisons treat it as, three of the four major providers here hold essentially the same core set, and even Apollo, the outlier, holds real independently audited certification rather than none at all. The real gap worth paying attention to isn’t which provider is GDPR-compliant, most of the credible ones are, it’s which one is ready for AI agents having direct, unsupervised access to the data — and on that specific, narrower question, the field is still short.
