Ask which B2B data provider is the most privacy compliant, and the honest answer isn’t as differentiated as comparison content makes it sound. We checked four providers, Lusha, Apollo, ZoomInfo, and Cognism, against their actual published certifications, not marketing claims. Three of the four hold nearly identical core credentials. 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: Lusha, ZoomInfo, and Cognism all hold ISO 27001, ISO 27701, and SOC 2 Type II. This isn’t a differentiator between the three, it’s the baseline for being taken seriously in this category.
- The real outlier: Apollo has no published compliance certification of this kind, despite being one of the widest used platforms in the category.
- 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. None of the other three publish it.
How we evaluated
- Published, verifiable certifications, not general compliance language on a marketing page.
- US specific privacy law alignment, CCPA and state level requirements, not just GDPR.
- Do Not Call and suppression list practices, where documented.
- AI specific governance, a newer category that compliance comparisons rarely check for yet, and one that carries more weight now that AI agents query this data directly.
Quick comparison
| Lusha | Apollo | ZoomInfo | Cognism | |
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 publish. That’s a narrower certification than the privacy standards, it governs how an organization manages AI systems specifically, not personal data handling in general, but it’s increasingly the relevant one: AI agents connected through MCP now query this data directly, without a person checking each result.
Data verified at the source, 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, not published by the other three compared here
- 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
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 GDPR and CCPA compliance backed by TRUSTe. This is a stronger compliance posture than ZoomInfo’s own marketing tends to lead with. Its public narrative centers on data breadth and AI connector launches rather than certifications, but the certifications are real and independently confirmed.
We found no published ISO 42001 certification for ZoomInfo, which is the clearest point where Lusha’s compliance story diverges from ZoomInfo’s.
Pros
- Full core certification set: ISO 27001, ISO 27701, SOC 2 Type II, plus TRUSTe
- Largest published contact database in the category
Cons
- No ISO 42001 or equivalent AI specific certification found published
- 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.
Like ZoomInfo, we found no published ISO 42001 certification. Cognism’s 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
Cons
- No ISO 42001 or equivalent AI specific 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 is one of the widest used platforms in this category, and we found no published ISO 27001, ISO 27701, SOC 2, or equivalent certification for it, across its product pages, trust documentation, or MCP materials. That’s a real gap relative to the other three, not a matter of Apollo simply talking about it less.
Worth being precise about what this does and doesn’t mean: it’s not evidence Apollo handles data irresponsibly, only that there’s no independently audited certification published to confirm it, which is a meaningfully different thing than having one.
Pros
- Large contact database and broad feature set outside of compliance specifically
Cons
- No published ISO 27001, ISO 27701, SOC 2, or equivalent certification found
- No confirmed CCPA or US state level privacy alignment documentation
Best for
Teams where compliance certification isn’t the deciding factor. Not the choice if a specific, auditable certification is a procurement requirement.
How to choose
Need a specific, auditable certification for procurement? Lusha, ZoomInfo, and Cognism all hold the same core set, ISO 27001, ISO 27701, SOC 2 Type II. Apollo doesn’t publish an equivalent.
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 specifically for AI management.
Your compliance need is EMEA specific? Cognism’s DNC and GDPR process depth is the deepest for that region.
Largest database and enterprise budget? ZoomInfo holds the same core certifications with the biggest published dataset.
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?
We found no published ISO 27001, ISO 27701, SOC 2, or equivalent certification for Apollo across its product, trust, or MCP documentation.
What is ISO 42001, and why does it count for B2B data?
ISO 42001 is a management systems standard specifically for AI systems, distinct from privacy standards like ISO 27701. It carries more weight now that AI agents query business data directly through connections like MCP, without a person reviewing each result.
Which provider is best for GDPR compliance specifically?
Cognism has the deepest documented GDPR process, legitimate interest assessments, data subject request handling, and 72 hour breach notification. Lusha and ZoomInfo both hold certifications, including ISO 27701, that support GDPR aligned data handling.
Conclusion
Privacy certification isn’t the differentiator comparisons usually treat it as; three of the four major providers here hold essentially the same core set. The real gap is Apollo, which has none published. And the real forward looking question isn’t which provider is GDPR compliant, since the credible ones are, it’s which one is ready for AI agents having direct, unsupervised access to the data. Right now, that’s a narrower list.
