Executive Summary

AI-generated analysis for Notion

Notion (notion.so) is a well-established SaaS productivity platform with a decade-long web presence, clean malware and sanctions records, and a strong foundational security posture including TLS 1.3, HSTS, and Cloudflare-backed infrastructure.

Area Requiring Attention

The platform claims a robust compliance portfolio — SOC 2, ISO 27001, ISO 27017, ISO 27018, HIPAA, GDPR, and CCPA — however none of these certifications could be independently verified through a public registry; all remain vendor-attested at this time. Two notable concerns elevate risk to Tier 3: the domain appears in 20 threat intelligence pulses associated with phishing campaigns, which is consistent with high-profile platforms being impersonated but warrants monitoring, and separately, two Hacker News discussions referenced AI-related data exfiltration vulnerabilities in Notion's platform. The absence of a publicly accessible subprocessor list limits supply chain visibility and is a meaningful gap for organizations with GDPR obligations.

Independence Statement

All evidence in this report was sourced independently from external data providers without vendor participation, notification, or input.

Investigation Findings

5 findings identified for Notion

4 medium1 low
medium

Missing Security Headers

notion.so is missing 2 recommended security headers: Content-Security-Policy, X-Frame-Options.

medium

Domain Not Found in RDAP

The domain "notion.so" was not found in any RDAP registry. This may indicate a very new, non-standard, or unregistered domain.

medium

Multiple Certificate Issuers (36)

notion.so has certificates from 36 different Certificate Authorities. This may indicate inconsistent certificate management practices.

medium

No Public Subprocessor Page Found

No accessible subprocessor page was found for notion.so. GDPR Article 28 requires data processors to maintain a list of subprocessors. Vendors with mature data governance typically publish this list.

low

No Email Infrastructure

notion.so has no MX records, meaning it cannot receive email directly.

Recommended Actions

Steps to address findings for Notion

  1. 1

    Within 14 days — Request SOC 2 Type II and ISO 27001 documentation directly from Notion's security team. Visit notion.so/security for contact options or email security@notion.so. Confirm the audit period covered and request a bridge letter if the SOC 2 report predates the last 12 months.

  2. 2

    Within 30 days — Obtain Notion's GDPR Article 28 subprocessor list. Contact privacy@notion.so and request either a direct list or the URL of their published subprocessor register. Document the list and establish a process to receive notifications of material subprocessor changes.

  3. 3

    Within 7 days — Brief internal end users on active Notion-themed phishing campaigns identified in threat intelligence feeds. Advise users to enable MFA on their Notion accounts, use bookmarked direct URLs rather than email links, and report suspicious login prompts to your security team.

  4. 4

    Before processing sensitive data — If Notion will process any protected health information, obtain and execute a signed HIPAA Business Associate Agreement (BAA) with Notion Labs, Inc. prior to data ingestion. Confirm BAA availability through notion.so/security.

  5. 5

    Ongoing — Monitor Notion's trust page (notion.so/security) for updates to certification status and subprocessor disclosures, and set a calendar reminder to re-request the SOC 2 Type II report annually.

Data Coverage Notes

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

  • Domain registration (WHOIS/RDAP) data for notion.so was not available — the .so TLD (Somalia ccTLD) has limited RDAP registry coverage, so domain age and registrant data could not be independently confirmed through this source. Web archive data independently confirms the domain has been active since at least January 2016.
  • External cyber risk scoring was not available for this assessment, meaning a quantitative third-party security rating could not be incorporated into the overall risk calculation.
  • Threat intelligence from one automated feed was partially unavailable; manual verification is available at the provided public URL. This represents a minor gap in threat signal coverage.
  • The Legal Entity Registry LEI match returned 'NOTION CAPITAL 2 LP' registered in the UK — this is a different legal entity (a venture capital fund) and is not the Notion productivity platform (Notion Labs, Inc.) under assessment. No LEI record was found for Notion Labs, Inc., which is expected for a US-incorporated private company.

The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending Notion a single email or waiting for a vendor response.
Is Notion safe to use as a vendor?+
Notion is a productivity vendor that handles organizational documents and communications. 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 Notion's full risk profile.
Does Notion have SOC 2 certification?+
Yes — Notion holds SOC 2 + 3 other certs. Rated Low Risk — 13 open ports detected. See all 7 findings →
Has Notion had any data breaches?+
Data breach history is an important signal for any vendor, particularly productivity platforms like Notion that handle organizational documents and communications. 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 Notion on any sanctions lists?+
Sanctions screening is standard due diligence for productivity vendors. ThirdProof screens Notion against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Notion or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Notion for vendor risk?+
Assessing Notion as a productivity vendor involves verifying SOC 2 Type II and FedRAMP 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.

Notion is in your vendor stack. Can you prove you assessed them?

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 Notion 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.
