Security Issues
About Security SEO
Website security is a confirmed Google ranking signal — HTTPS has been a ranking factor since 2014, and Google Chrome marks non-HTTPS sites with a 'Not Secure' warning that devastates user trust and conversion rates. But security SEO extends far beyond SSL certificates. Mixed content errors (loading HTTP resources on HTTPS pages) trigger browser warnings and can prevent page rendering. Vulnerable or outdated server software exposes your site to injection attacks that can result in Google's 'This site may be hacked' warning — a penalty that typically reduces organic traffic by 90% or more overnight. Security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security protect against XSS attacks, clickjacking, and protocol downgrade attacks while also signaling to search engines that your site follows security best practices. For e-commerce and financial sites, PCI compliance and proper handling of sensitive data are additional ranking considerations. This reference covers every security issue Digispot AI checks during audits, providing severity ratings aligned with OWASP guidelines and clear remediation steps to protect both your users and your search rankings.
Problem
Website is not served over HTTPS
Impact
Data transmission is not encrypted, vulnerable to man-in-the-middle attacks
critical ImpactHow to Fix
Install SSL certificate and enforce HTTPS
Problem
SSL certificate has expired or is expiring very soon (within 14 days)
Impact
Browsers will show security warnings, potentially blocking access
critical ImpactHow to Fix
Renew SSL certificate immediately
Problem
HSTS header is not configured
Impact
Vulnerable to SSL stripping attacks
high ImpactHow to Fix
Implement HSTS with appropriate max-age
Problem
Page contains mixed (HTTP/HTTPS) content
Impact
Reduces security and triggers browser warnings
high ImpactHow to Fix
Update all resource references to use HTTPS
Problem
SSL certificate will expire within 30 days
Impact
Certificate should be renewed soon to prevent security warnings
medium ImpactHow to Fix
Plan certificate renewal within the next few weeks
Problem
Self-signed SSL certificate detected
Impact
Browsers will show security warnings and may block access, reducing user trust
critical ImpactHow to Fix
Replace with a certificate from a trusted Certificate Authority (CA)
Problem
Weak encryption cipher suites detected
Impact
Vulnerable to cryptographic attacks and may not meet security standards
high ImpactHow to Fix
Disable weak ciphers and use only strong, modern cipher suites
Problem
SSL certificate does not match the domain name
Impact
Browsers will show security warnings and may block access
critical ImpactHow to Fix
Install a certificate that matches the domain name or update certificate configuration
Problem
Outdated TLS version detected (TLS 1.0 or 1.1)
Impact
Vulnerable to known security vulnerabilities, may not meet compliance requirements
high ImpactHow to Fix
Disable TLS 1.0 and 1.1, use TLS 1.2 or higher
Problem
HTTP/2 protocol is not enabled
Impact
Missed performance benefits and modern protocol features
low ImpactHow to Fix
Enable HTTP/2 on the server for improved performance and security
Problem
Content Security Policy (CSP) header is missing
Impact
Vulnerable to XSS attacks and unauthorized resource loading
high ImpactHow to Fix
Implement Content Security Policy header to restrict resource loading
Problem
Content Security Policy is too permissive or uses unsafe directives
Impact
Reduced protection against XSS and injection attacks
medium ImpactHow to Fix
Strengthen CSP by removing unsafe-inline and unsafe-eval, use nonces or hashes
Problem
X-Frame-Options header is missing
Impact
Vulnerable to clickjacking attacks
high ImpactHow to Fix
Add X-Frame-Options header with DENY or SAMEORIGIN value
Problem
X-Content-Type-Options: nosniff header is missing
Impact
Vulnerable to MIME type sniffing attacks
medium ImpactHow to Fix
Add X-Content-Type-Options: nosniff header
Problem
Certificate Authority Authorization (CAA) DNS record is missing
Impact
Cannot restrict which CAs can issue certificates for your domain
medium ImpactHow to Fix
Add CAA DNS records to specify authorized certificate authorities
Problem
DNSSEC is not enabled for the domain
Impact
Vulnerable to DNS spoofing and cache poisoning attacks
low ImpactHow to Fix
Enable DNSSEC at your DNS provider
Problem
Sensitive information is exposed in headers or error messages
Impact
May reveal system details that could aid attackers
medium ImpactHow to Fix
Remove or sanitize sensitive information from headers and error messages
Problem
Vulnerable JavaScript libraries or dependencies detected
Impact
Known security vulnerabilities may be exploited
high ImpactHow to Fix
Update vulnerable libraries to patched versions
Problem
SSL certificate has invalid date range (not yet valid or already expired)
Impact
Certificate will not be trusted, browsers will show security warnings
critical ImpactHow to Fix
Check system clock and certificate validity dates, renew if necessary
