Website Security Scanner & Monitoring for Modern Teams
SiteSecura replaces enterprise jargon with fast, non-intrusive cybersecurity evaluations. Instantly evaluate SSL/TLS encryption, security headers, DNS email authentication, and cookie defenses with a transparent 0–100 deterministic security score.
Core Defensive Web Security Capabilities
Comprehensive, non-intrusive assessments across the six foundational pillars of modern web security hygiene.
Deterministic Security Scoring
Every assessment calculates a transparent 0 to 100 mathematical score starting from a base of 100 points. Deductions apply across five weighted categories: HTTPS/SSL (30 pts), Security Headers (25 pts), DNS & Email (20 pts), Server Hygiene (15 pts), and Cookie Security (10 pts). Scores map strictly to risk levels: Excellent (90–100), Good (75–89), Medium Risk (60–74), High Risk (40–59), and Critical Risk (0–39).
SSL & TLS Certificate Auditing
Deep inspection of transport-layer encryption certificates, trust paths, and protocol handshakes. Validates Certificate Authority (CA) trust chains, Subject Alternative Names (SAN), and expiration countdowns. Identifies support for TLS 1.3 and TLS 1.2, and flags deprecated protocols (SSLv3, TLS 1.0, TLS 1.1) or weak cipher suites to prevent browser security warnings and interception.
DNS, SPF & DMARC Email Authentication
Audits public DNS records for SPF syntax (v=spf1), DMARC policy enforcement (v=DMARC1 at _dmarc.domain), and DNSSEC validation to protect brand reputation against domain spoofing.
HTTP Security Headers Inspection
Evaluates browser-enforced defense headers that stop client-side exploitation. Inspects Strict-Transport-Security (HSTS with includeSubDomains and preload), Content-Security-Policy (CSP), X-Frame-Options (clickjacking mitigation), X-Content-Type-Options (MIME-sniffing prevention), and Referrer-Policy.
Cookie Security Inspection
Inspects all Set-Cookie headers issued by your server for vital defense flags. Verifies the Secure attribute (enforcing encrypted HTTPS transit), HttpOnly (blocking JavaScript access to prevent session theft), and SameSite (Strict or Lax) to neutralize CSRF attacks.
Website Technology Detection
Passive fingerprinting that identifies underlying web servers (Nginx, Apache, Cloudflare, Caddy), content management systems (WordPress, Drupal), and application frameworks without intrusive probing. Flags exposed Server and X-Powered-By version disclosures that advertise known CVE vulnerabilities to attackers.
Actionable Findings with Ready-to-Deploy Fixes
We don't just point out problems—SiteSecura provides copy-ready configuration directives and plain-English remediation guidance for every detected issue.
Prioritized Severity Tiers
Findings are classified into Critical, High, Warning, Info, and Pass so your engineering team knows exactly what to tackle first.
Drop-In Server Configuration Snippets
Copy-paste directives tailored for Nginx, Apache, and Cloudflare response header transform rules. Eliminate guesswork and save hours of developer research.
Traceable Mathematical Impact
Every finding shows its exact point deduction. Fix an issue, re-scan in 15 seconds, and watch your security score rise immediately.
Missing Content-Security-Policy (CSP) Header
The web server does not issue a Content-Security-Policy response header, leaving browsers vulnerable to Cross-Site Scripting (XSS), malicious iframe embedding, and untrusted asset injection.
# /etc/nginx/conf.d/security-headers.conf
# Baseline defensive headers - customize allowed origins for your app
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' data:; connect-src 'self'; object-src 'none'; frame-ancestors 'self'; base-uri 'self'; form-action 'self';" always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-Frame-Options "SAMEORIGIN" always;Advanced Security Capabilities for Teams & Agencies
Enhanced tools designed for engineering teams managing critical production sites and digital agencies overseeing client portfolios.
AI Security Advisor
Integrates contextual LLM intelligence to evaluate your website's specific audit findings and generate tailored remediation roadmaps. Translates complex vulnerabilities into step-by-step developer checklists, framework-specific code snippets, and executive summaries for leadership.
SiteSecura Verified Trust Badge
Demonstrate your defensive cybersecurity posture to visitors with an embeddable SVG or iframe trust badge. Badges automatically reflect your website's latest scan and are available for qualifying domains achieving a verified score of 75 or higher.
Deep Website Crawl & Attack Surface Discovery
Go beyond single-page testing. Performs a bounded multi-page crawl (up to 50 pages on Pro, 100 pages on Agency at depth 2) to evaluate your domain structure, discovering observable internal assets, identifying broken mixed-content HTTP links, and auditing frontend third-party script dependencies.
Interactive Security Configuration Utilities
Access a full suite of free standalone security utilities for instant debugging and validation. Includes our CSP Policy Analyzer, DNS Lookup Tool, HTTP Status & Redirect Tracer, Robots.txt & Sitemap Checker, and security.txt Validator.
Automated Monitoring & Professional PDF Reporting
Maintain continuous visibility into configuration drift and share polished, audit-ready security reports with stakeholders.
Automated Scheduled Monitoring & Drift Alerts
Website security isn't static. Software deployments, CDN updates, and DNS modifications can inadvertently drop defensive headers or break encryption chains. SiteSecura scans your portfolio in the background so you know before your visitors or clients do.
- Flexible Monitoring Cadence: Weekly automated scans on Basic; daily scans on Pro and Agency.
- 14-Day SSL Expiry Warnings: Proactive alerts dispatched 14 days before certificate expiration to eliminate downtime.
- Security Drift Notifications: Instant alerts if security headers drop, DNS changes occur, or your score decreases.
- Security Health Timeline: 30 to 365 days of historical posture tracking to demonstrate compliance progress.
Executive PDF Reports & White-Label Branding
Transform technical findings into clear, beautifully formatted PDF audit reports ready for management, clients, cyber-insurance underwriters, and compliance reviews.
- Free Plan Preview: Watermarked PDF summary showing overall score, posture grade, and top findings.
- Full Technical Audit Reports: Unredacted findings, technical evidence, and step-by-step remediation commands.
