Executive Summary

AI-generated analysis for Apollo.io

Apollo.io presents a Low Risk (Tier 4) posture with a 94% confidence score, supported by clean threat intelligence across 94 security engines, no sanctions matches, and no adverse media.

Area Requiring Attention

The domain is well-established with significant web traffic, operates behind Cloudflare's CDN infrastructure, and maintains a public trust page (trust.apollo.io) where multiple security certifications are claimed. Two areas warrant attention prior to onboarding: the HTTP security header configuration falls below best-practice standards (C+ grade), and all four claimed certifications — including SOC 2 and ISO 27001 — are vendor-attested only, requiring independent confirmation through direct document requests. For a retail context, Apollo.io's role as a sales intelligence and GTM platform means it is unlikely to be in scope for the cardholder data environment, but its handling of consumer contact data under CCPA/GDPR requires formal Data Processing Agreement review before deployment.

Independence Statement

All evidence underlying this assessment was sourced independently from third-party data providers and public registries without vendor participation or notification.

Steps to address findings for Apollo.io

  1. 1

    Request Apollo.io's SOC 2 Type II audit report within 30 days — contact their security team at trust.apollo.io or email security@apollo.io. If the most recent report is older than 12 months, request a bridge letter from their auditor confirming continued compliance. This is the highest-priority action for PCI-DSS TPSP documentation.

  2. 2

    Request and execute a signed Data Processing Agreement (DPA) covering GDPR Article 28 requirements and a CCPA service provider addendum prohibiting the sale or sharing of consumer data. Apollo.io's DPA may be available at trust.apollo.io — check the 'Documents' section under 'Private' access, which may require a request to their legal or sales team.

  3. 3

    Obtain Apollo.io's ISO 27001 certificate from their security team — request the certificate document showing the issuing certification body (e.g., BSI, Bureau Veritas), current validity period, and certification scope. This should confirm whether the 'recertification' referenced on their trust page is current.

  4. 4

    Verify that HTTP security headers — specifically Strict-Transport-Security (HSTS), Content-Security-Policy, and X-Frame-Options — are enforced at the application layer. Ask Apollo.io's security team to confirm their header configuration, noting that Cloudflare CDN edge behavior may differ from their origin server settings. Request their HTTP Observatory remediation plan if headers remain misconfigured.

  5. 5

    Confirm Apollo.io's MFA enforcement policy for all user accounts before provisioning access. Given the credential exhaustion threat intelligence context, verify that your organization's Apollo.io admin accounts are protected by SSO/MFA and that unused user accounts are deprovisioned promptly.

  6. 6

    Retain this assessment report, the signed DPA, and the SOC 2 Type II report in your TPSP documentation file alongside Apollo.io's entry in your PCI-DSS 12.8 TPSP register. Your QSA will request this evidence during assessment fieldwork.

Data Coverage Notes

Some data sources may have had limited availability during this assessment. This does not reflect negatively on the vendor.

  • SSL/TLS deep configuration analysis was unavailable from one supplementary source. The primary SSL assessment (via domain analysis) confirmed a valid Let's Encrypt certificate expiring May 15, 2026, with 72 days remaining at time of assessment. A certificate renewal reminder is advisable.
  • Certificate Transparency log data was unavailable, limiting visibility into the full subdomain inventory issued under apollo.io. This prevents a comprehensive review of historical certificate issuance patterns.
  • Web archive history data was unavailable, preventing independent confirmation of domain establishment date. threat intelligence engine data indicates the domain was created January 9, 2018, providing partial corroboration.
  • Domain RDAP registration data returned a 404 response, which is common for .io TLD domains due to limited RDAP registry support for ccTLDs. This should not be interpreted as a registration concern.

The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending Apollo.io a single email or waiting for a vendor response.
Is Apollo.io safe to use as a vendor?+
Apollo.io is a sales vendor that handles organizational data. Safety depends on their current security posture, certification status, and how they handle your specific data. ThirdProof automates this evaluation across 27 intelligence sources — sanctions databases (OFAC, EU, UN), business registration verification, adverse media scanning, and cyber risk assessment — producing a deterministic risk tier with confidence score plus an auto-filled security questionnaire. Run a free investigation to see Apollo.io's full risk profile.
Does Apollo.io have SOC 2 certification?+
No SOC 2 found. Apollo.io rated . See all 0 findings →
Has Apollo.io had any data breaches?+
Data breach history is an important signal for any vendor, particularly sales platforms like Apollo.io that handle organizational data. ThirdProof's adverse media analysis searches multiple news APIs and public records for data breaches, security incidents, lawsuits, regulatory enforcement actions, and financial distress signals. Each finding is linked to its original source with severity classification.
Is Apollo.io on any sanctions lists?+
Sanctions screening is standard due diligence for sales vendors. ThirdProof screens Apollo.io against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Apollo.io or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Apollo.io for vendor risk?+
Assessing Apollo.io as a sales vendor involves verifying SOC 2 Type II and applicable industry standards compliance, reviewing their subprocessor chain, and checking sanctions exposure. ThirdProof automates this across 27 intelligence sources in an average of 7 minutes — no questionnaires or vendor participation required. Your first 5 investigations are free.
How long does a ThirdProof assessment take?+
A ThirdProof assessment completes in an average of 7 minutes. 27 intelligence sources are queried in parallel — sanctions databases, business registries, threat intelligence feeds, certificate transparency logs, and more. The result is a deterministic risk tier with confidence score and audit-ready PDF report.
Is ThirdProof free?+
ThirdProof offers 5 free vendor assessments with no credit card required. Each assessment includes the full report — risk tier, confidence score, individual findings, executive summary, and PDF export. Paid plans start at $399/month for teams that need ongoing vendor monitoring.
Can I use a ThirdProof report as SOC 2 audit evidence?+
Yes. ThirdProof reports are designed to satisfy SOC 2 CC9.2 (vendor risk management) requirements. Each report includes SHA-256 integrity verification, methodology disclosure, source attribution for every finding, and AI content labeling. Auditors can independently verify the report's authenticity and trace each finding to its original source.
How is ThirdProof different from a security questionnaire?+
Security questionnaires require vendor participation, take weeks, and produce self-reported answers. ThirdProof queries 27 independent intelligence sources — no vendor involvement needed. Risk tiers are assigned by a deterministic rules engine (not AI opinion), and every finding links to its original source. You get an audit-ready report in an average of 7 minutes instead of waiting weeks for a questionnaire response.

Apollo.io is used by your team. Have you assessed their risk?

SOC 2 CC9.2, HIPAA, PCI-DSS, and CMMC all require documented vendor due diligence — not just knowing the answer, but having audit-ready evidence you verified it. Most compliance teams can't produce that documentation on demand.

ThirdProof investigates Apollo.io across 27 intelligence sources in an average of 7 minutes — sanctions screening, cyber posture, SOC 2 verification, FedRAMP status, and more. Every investigation produces two deliverables: an audit-ready risk report and an auto-filled security questionnaire your prospects and auditors expect to see.
