SaaSFort When an enterprise procurement team asks for “OWASP compliance evidence,” most B2B SaaS CTOs know what OWASP is — but few know which of the Top 10 categories enterprise security teams actually scrutinize closely.
This guide breaks down the OWASP Top 10 from the procurement perspective: not just what each vulnerability means technically, but what enterprise InfoSec teams look for in vendor assessments.
The OWASP Top 10 (2021) — Enterprise Procurement Lens
A01: Broken Access Control
What it is: Users can access resources or perform actions they shouldn’t be authorized for.
What enterprise buyers check:
- Can one customer’s data be accessed by another customer? (Multi-tenancy isolation)
- Can a standard user escalate to admin privileges?
- Are API endpoints protected with proper authorization checks?
Procurement red flag: Any evidence of IDOR (Insecure Direct Object Reference) vulnerabilities — these are catastrophic for enterprise buyers because they imply data leakage between tenant organizations.
How to demonstrate compliance: Automated scans should verify authorization checks on all authenticated endpoints. Include specific mention of multi-tenancy isolation testing in your report.
A02: Cryptographic Failures
What it is: Sensitive data exposed due to weak or missing encryption.
What enterprise buyers check:
- Is data encrypted in transit (TLS 1.2+, no deprecated ciphers)?
- Is sensitive data encrypted at rest?
- Are API keys and secrets handled securely (not logged, not in URLs)?
Procurement red flag: TLS grade below A (check via SSL Labs), HTTP endpoints that redirect to HTTPS rather than enforcing HTTPS directly.
How to demonstrate compliance: SSL/TLS scan results with grade + cipher suite list. Explicit statement that no sensitive data is logged.
A03: Injection
What it is: SQL injection, command injection, LDAP injection — attacker-controlled input executed as code.
What enterprise buyers check:
- Are all user inputs sanitized and parameterized?
- Is the application resistant to SQL injection on login and search endpoints?
Procurement red flag: Any finding of SQL injection — even low-severity. Enterprise buyers treat this as a fundamental failure of secure development practice.
How to demonstrate compliance: Dynamic scan results showing injection testing performed on all input fields with zero findings.
A04: Insecure Design
What it is: Missing or ineffective security controls at the design level — not just implementation bugs.
What enterprise buyers check:
- Are there rate limits on authentication endpoints?
- Is there protection against brute-force attacks?
- Are password reset flows resistant to account enumeration?
Procurement red flag: No rate limiting on login endpoints is increasingly flagged by enterprise CISOs.
A05: Security Misconfiguration
What it is: Incorrectly configured permissions, unnecessary features enabled, default credentials.
What enterprise buyers check:
- Are security headers present? (Content-Security-Policy, X-Frame-Options, HSTS, X-Content-Type-Options)
- Is directory listing disabled?
- Are debug endpoints, admin panels, or staging environments publicly accessible?
Procurement red flag: Missing HSTS header or low CSP score. Easily caught by automated scanners and easily fixed — having these issues in a formal scan looks bad.
How to demonstrate compliance: Header scan results showing all security headers configured. This is one of the easiest wins.
A06: Vulnerable and Outdated Components
What it is: Using libraries or frameworks with known CVEs.
What enterprise buyers check:
- How do you track CVEs in your dependencies?
- What is your process for applying security patches?
- How quickly do you patch critical CVEs?
Procurement red flag: A dependency with a known critical CVE (CVSS 9+) that’s been public for >30 days without a patch. This is increasingly common in enterprise questionnaires.
How to demonstrate compliance: CVE tracking report showing current dependency versions, known CVE status, and patch timeline history.
A07: Identification and Authentication Failures
What it is: Weak authentication mechanisms — no MFA, weak password policies, insecure session management.
What enterprise buyers check:
- Does your application support SSO / SAML / OIDC? (Critical for larger enterprise)
- Is MFA available for admin accounts?
- What are your session timeout policies?
Procurement red flag for enterprise deals: No SSO support is a deal-blocker for many enterprise security policies. Make sure your roadmap addresses this.
A08: Software and Data Integrity Failures
What it is: Insecure deserialization, untrusted CI/CD pipeline inputs, software supply chain attacks.
What enterprise buyers check (post-SolarWinds, post-Log4Shell):
- Do you have supply chain security practices?
- Is your CI/CD pipeline protected?
- Do you verify the integrity of third-party packages?
A09: Security Logging and Monitoring Failures
What it is: Not detecting, escalating, or responding to security breaches.
What enterprise buyers check:
- Do you log authentication events (success and failure)?
- Do you have alerting on suspicious activity?
- What is your MTTD (Mean Time to Detect)?
Procurement red flag: No documented incident detection or response process.
A10: Server-Side Request Forgery (SSRF)
What it is: Application fetching remote resources based on user-supplied input, potentially accessing internal services.
What enterprise buyers check: Relevant for SaaS products that integrate with customer-specified URLs (webhooks, integrations) — a common attack vector for internal network access.
Building Your OWASP Evidence Package
For a procurement-ready OWASP evidence package, you need:
- Scan report — dated within 6 months, covering all 10 categories. SaaSFort’s scanner covers all OWASP Top 10 categories with an A–F grade that procurement teams understand instantly
- Finding list — with severity, CVSS score, and current status (open/remediated)
- Remediation timeline — showing how quickly you address findings by severity
- Attestation — brief statement from CTO confirming the scope of testing
The key: findings aren’t a problem. Every application has some. What enterprise buyers want to see is that you know about them and have a process to address them. For the full list of questions enterprise procurement teams ask, see our 50-point vendor security assessment checklist.
Frequently Asked Questions
What is the difference between OWASP compliance and SOC 2 certification?
OWASP is a technical application security standard that tests your software for specific vulnerabilities. SOC 2 is an organizational audit that evaluates your company’s security controls and processes. A SOC 2 report confirms you have a vulnerability management process; an OWASP scan proves your application is actually secure. Enterprise buyers increasingly require both. See our detailed comparison: SOC 2 vs OWASP: Which Actually Closes Enterprise Deals?
How often should SaaS vendors run OWASP scans?
According to SaaSFort’s analysis, enterprise procurement teams expect evidence of scanning within the last 90 days. Best practice is weekly automated scans with continuous monitoring for critical categories (A01: Broken Access Control, A02: Cryptographic Failures, A03: Injection). Companies using continuous security monitoring close enterprise deals 3–4 weeks faster than those relying on annual pen tests.
Do enterprise buyers accept automated OWASP scans instead of manual pen tests?
Most enterprise procurement teams accept automated scanning for 80% of their security assessment requirements. The remaining 20% — business logic testing and complex authorization flows — still benefits from annual manual pen testing. The optimal approach is continuous automated scanning year-round plus one annual pen test, reducing costs by 50–70% while increasing coverage from 14 days to 365 days per year.
Which OWASP categories are most critical for enterprise deal approval?
Based on analysis of hundreds of DDQs, the top 3 deal-blocking categories are: A01 (Broken Access Control) — any multi-tenancy isolation failure is catastrophic; A02 (Cryptographic Failures) — TLS grade below A triggers immediate flags; and A05 (Security Misconfiguration) — missing security headers like HSTS and CSP are easily detected and easily fixed, making their absence look negligent. For a complete vendor security assessment checklist, see our 50-point guide.
How does OWASP compliance help with NIS2 and DORA requirements?
OWASP scanning directly supports NIS2 Article 21(2)(e) vulnerability handling requirements and DORA Article 9 ICT risk management obligations. Enterprise buyers in regulated sectors now include OWASP evidence in their NIS2 vendor compliance checklists and DORA digital resilience assessments. For a complete breakdown of every Article 21 technical measure and how to implement it, see our NIS2 technical security requirements guide. Demonstrating OWASP compliance provides concrete evidence for multiple regulatory frameworks simultaneously.
