Your website is your company's digital storefront — and simultaneously the largest publicly visible attack surface. Attackers don't need sophisticated techniques when basic security settings are missing. An automated security check reveals in minutes what a manual review wouldn't find in weeks.
What a Website Security Check Examines
A comprehensive scan examines 15 security-relevant areas of your public web presence:
SSL & Encryption
- SSL Certificate: Validity, expiration date, certificate chain, TLS version
- HTTP-to-HTTPS Redirect: Are all requests correctly redirected to the encrypted connection?
An expired or misconfigured SSL certificate shows visitors a warning page. This costs not just trust — Google penalizes it in rankings too.
Security Headers
HTTP security headers are the invisible protective layer of your website. The most important ones:
- Content-Security-Policy (CSP): Prevents cross-site scripting (XSS) by only allowing trusted sources for scripts
- X-Frame-Options: Protects against clickjacking attacks
- Strict-Transport-Security (HSTS): Enforces encrypted connections
- X-Content-Type-Options: Prevents MIME sniffing
According to SecurityHeaders.com analysis, over 70% of business websites are missing at least three critical security headers.
Email Security
Even if your website is secure — without correct email authentication, attackers can abuse your domain for phishing:
- SPF: Defines which servers may send emails for your domain
- DKIM: Cryptographically signs outgoing emails
- DMARC: Determines how receiving servers handle unauthenticated emails
- DANE/TLSA: Enforces TLS encryption for email transport
DNS & Infrastructure
- DNSSEC: Protects DNS responses from manipulation
- Open Ports: Unnecessarily open network services increase the attack surface
- Subdomains: Forgotten test or staging subdomains are frequently unsecured
- Domain Expiry: An expiring domain name can be registered by third parties
Web Configuration
- Web Application Firewall (WAF): Is a WAF active and correctly configured?
- security.txt: Does your website provide a standardized security contact?
- Cookie Configuration: Are session cookies protected with Secure, HttpOnly, and SameSite flags?
- Technology Stack: Does your server publish version details that make attackers' work easier?
Why Automated Scans Matter
A manual security review is thorough but time-consuming and expensive. Automated scans deliver a complete picture of the publicly visible security posture in minutes. They don't replace a penetration test — but they uncover the 80% of vulnerabilities caused by missing configuration.
The crucial advantage: regular scans detect degradation. An SSL certificate that's valid today expires in three months. A security header that's set today disappears during the next website update. Only regular checking creates sustainable security.
The Score: 0 to 100
A structured security check summarizes all results in a score from 0 to 100. Green, yellow, red — at a glance you see where your website stands and where action is needed. Each finding comes with a concrete recommendation and priority level.
GDPR Relevance
GDPR Article 32 requires "appropriate technical and organizational measures" to protect personal data. An unencrypted website, missing security headers, or open ports can be considered a violation of this requirement — especially when contact forms or customer portals are affected.
