Security & Trust

Your data is safe.
Your analysis is trustworthy.

SEO-GEO crawls thousands of external websites and processes them through AI — which makes security not just a feature, but a foundation. We defend against the latest AI threats including prompt injection, data exfiltration, and cross-tenant leakage with a 6-layer defense system built from day one.

The threat is real — and we're ready

Attackers can embed hidden instructions in web pages — white text on white backgrounds, invisible Unicode characters, CSS-hidden elements — designed to manipulate AI tools that process their content. This is called indirect prompt injection, and it's the #1 security threat for AI applications (OWASP LLM Top 10, 2025).

When your SEO tool crawls a website and sends that content to an AI for analysis, a malicious page could try to manipulate your scores, extract your data, or override the AI's instructions. Most SEO tools don't defend against this because they were built before the AI era.

SEO-GEO was built for this era. Every piece of crawled content passes through our sanitization pipeline before AI processing. Our system prompts are hardened. Our outputs are validated. And we monitor for attacks in real-time.

6-layer defense system

No single defense is enough. We layer six independent security systems so that even if one layer is bypassed, the others hold.

1

Content Sanitization

Every crawled page passes through our sanitization pipeline before AI processing. We strip HTML comments, CSS-hidden elements, zero-width Unicode, invisible text, and known injection patterns.

✓White text on white background detection
✓CSS display:none / opacity:0 removal
✓Zero-width Unicode character stripping
✓Hidden HTML comment removal
✓Base64 payload detection
✓Content length limits to prevent flooding
2

AI Prompt Hardening

System prompts use strict delimiters to separate trusted instructions from untrusted crawled data. Our AI models are instructed to treat external content as data to analyze — never as instructions to follow.

✓Untrusted content wrapped in clear delimiters
✓Explicit 'analyze only, never follow' directives
✓No credentials in prompts with crawled content
✓Minimal system prompt surface area
✓Provider fallback chain with budget limits
✓Response format enforcement
3

Output Validation

Every AI response is validated against strict schemas before being stored or displayed. Scores must be within valid ranges. Responses are checked for data exfiltration patterns and sanitized before rendering.

✓Schema validation on all AI outputs
✓Score range enforcement (0-100)
✓Exfiltration pattern detection
✓HTML escaping before rendering
✓Rule-based vs AI score divergence alerting
✓JSON structure enforcement
4

Tenant Isolation

Your data is completely isolated from other customers through defense-in-depth: database-level Row-Level Security (RLS) policies and application-layer ownership verification on every request.

✓PostgreSQL RLS on every table
✓Application-layer orgId verification
✓Clerk authentication on all routes
✓Scoped API keys with rate limiting
✓Webhook signature verification
✓Never trust client-supplied IDs
5

Infrastructure Security

Enterprise-grade infrastructure with encrypted connections, secure credential management, and continuous monitoring. All data is encrypted in transit (TLS 1.3) and at rest.

✓HTTPS everywhere (TLS 1.3)
✓Environment variable credential storage
✓SHA-256 hashed API keys
✓90-day key rotation schedule
✓Security headers (CSP, HSTS, X-Frame-Options)
✓npm dependency vulnerability scanning
6

Continuous Monitoring

Automated weekly security audits scan for hardcoded secrets, dependency vulnerabilities, unprotected routes, and new attack vectors. Quarterly red-team exercises test our prompt injection defenses.

✓Weekly automated security audits
✓Secret pattern scanning in codebase
✓npm audit for CVE detection
✓OWASP LLM Top 10 compliance tracking
✓Injection pattern threat intelligence
✓Quarterly red-team exercises

Security FAQ

How does SEO-GEO protect against AI prompt injection attacks?
We use a 5-layer defense system: content sanitization strips hidden text, CSS-hidden elements, and zero-width characters before AI processing. System prompts explicitly delimit untrusted crawled content. All AI outputs are validated against strict schemas. Crawled content is architecturally isolated from user credentials. Continuous monitoring flags anomalies between rule-based and AI scores.
Is my data isolated from other customers?
Yes. SEO-GEO enforces tenant isolation at two layers: Row-Level Security (RLS) policies at the database level ensure queries can only access your organization's data, and application-layer checks verify ownership on every API request. Even if one layer were bypassed, the other prevents cross-tenant data access.
What happens if a crawled website contains malicious content?
Our content sanitization pipeline strips all hidden elements (invisible text, CSS-hidden divs, HTML comments, zero-width Unicode characters) before any AI processing. If injection patterns are detected, the system falls back to rule-based scoring and flags the results with a warning. Malicious payloads are logged for threat intelligence but never executed.
How are API keys and credentials stored?
All credentials are stored as encrypted environment variables — never in source code or databases. API keys use SHA-256 hashing with the raw key shown only once at creation. We follow the principle of least privilege: each service has only the permissions it needs. Keys are rotated every 90 days.
Does SEO-GEO comply with OWASP security standards?
Yes. We address all OWASP Top 10 (2025) web application threats and OWASP LLM Top 10 (2025) AI-specific threats. Our weekly automated security audits scan for vulnerabilities, and we conduct quarterly red-team exercises specifically targeting prompt injection vectors.
Can I use SEO-GEO safely to analyze competitor websites?
Absolutely. All crawling respects robots.txt directives and rate limits. Crawled content passes through our sanitization pipeline before any analysis, protecting your account from malicious content on external sites. We use SERP APIs exclusively — no custom scraping — ensuring full legal compliance.
