What a website security check is
A website security check is a systematic scan of your website to identify vulnerabilities, misconfigurations, and weaknesses that attackers could exploit. It examines your site from the outside — the same perspective a real attacker would have — and reports what it finds.
Think of it as a health check for your website. You might feel fine, but the check reveals issues you didn't know existed — issues that could cause serious problems if left untreated.
What a security check covers
A thorough website security check examines multiple layers:
SSL/TLS configuration
Whether your site uses HTTPS correctly, whether your certificate is valid and up to date, and whether the encryption protocols are current. Outdated TLS versions (1.0, 1.1) are known to be vulnerable.
Security headers
HTTP response headers that protect against common attacks. Key headers include Content-Security-Policy (prevents code injection), Strict-Transport-Security (forces HTTPS), X-Frame-Options (prevents clickjacking), and X-Content-Type-Options (prevents MIME sniffing).
Software versions
Whether your CMS, plugins, themes, and server software are up to date. Outdated software is one of the most common attack vectors — known vulnerabilities have published exploits that anyone can use.
Common vulnerabilities
Testing for the OWASP Top 10 — the most critical security risks to web applications. This includes SQL injection, cross-site scripting (XSS), broken authentication, and security misconfigurations.
Information exposure
Whether your site leaks sensitive information — server versions in headers, directory listings, error messages with stack traces, backup files accessible from the web, or configuration files that should be private.
DNS and email security
Whether your domain has SPF, DKIM, and DMARC records configured to prevent email spoofing. Attackers often impersonate businesses via email — these records help prevent that.
Why growing businesses are targets
A common misconception is that attackers only target large organisations. In reality, growing businesses are the most frequent targets because:
- Lower security investment — Smaller businesses typically have fewer security measures in place
- Valuable data — Customer data, payment information, and business records are valuable regardless of company size
- Automated attacks — Most cyber attacks are automated. Bots scan the entire internet for vulnerable sites — they don't care how big your business is
- Supply chain access — Compromising a small business can provide access to their larger clients and partners
What a security check report looks like
A good security check report includes:
- Executive summary — An overview of your security posture in plain language
- Findings by severity — Issues categorised as critical, high, medium, or low risk
- Specific details — What was found, where, and why it matters
- Remediation steps — Clear instructions for fixing each issue
- Priority order — What to fix first based on risk and impact
Security check vs penetration test
A security check is a broad scan that identifies known vulnerabilities and misconfigurations. A penetration test (VAPT) goes deeper — a security professional actively tries to exploit the vulnerabilities to prove real-world impact. Think of a security check as finding the unlocked doors, and a pentest as walking through them to see what's inside.
Most businesses should start with a security check and progress to a full VAPT based on the findings.
