Web Application Protection
21.2%
Vulnerable to Session Hijacking
47%
Vulnerable to Content Injection
31.8%
Vulnerable to Clickjacking
77.3%
Server Fingerprint Exposed

Missing security headers expose web applications to clickjacking, injection, and man-in-the-middle attacks.

Email Spoofing Protection
9.1%
Vulnerable to Email Impersonation
9.1%
Sender Identity Unverified
6.1%
No Email Authentication

Organizations without proper email authentication controls allow attackers to impersonate their domain — enabling phishing campaigns and business email compromise.

DNS & Domain Security
54.5%
Domain Resolution Unprotected
63.6%
Unauthorized Certificate Issuance Possible
10.6%
Unencrypted Access Possible

Unprotected domain infrastructure allows attackers to intercept resolution and issue unauthorized certificates — redirecting customers to attacker-controlled systems.

Encryption & Disclosure Readiness
84.8%
Modern Encryption Adopted
36.4%
Coordinated Disclosure Program
16.7%
Session Token Exposure Risk
12.1%
Cookies Missing HttpOnly

Modern encryption standards and coordinated disclosure programs demonstrate security maturity. Weak session management exposes user credentials to interception.

Unauthorized Access Vectors
4.5%
Unencrypted File Transfer Open
1.5%
Remote Desktop Accessible
1.5%
Mail Server Directly Accessible
3%
Database Port Accessible

Exposed administrative interfaces provide direct attack vectors for unauthorized access and lateral movement across internal systems.

Technology Maturity
12.1%
CDN Protected
13.6%
Management Panel Accessible
7.6%
Self-Signed Certificate
6.1%
End-of-Life Software

Modern infrastructure investment correlates with lower breach probability. Exposed administration panels and legacy software create easily exploitable entry points.

Certificate & Vulnerability Management
3%
Expiring <30d
15.2%
Known Exploitable Vulnerabilities
6.1%
Active Exploitation (CISA KEV)

Expired or expiring certificates cause service disruptions and reduce trust. Known CVEs indicate unpatched, exploitable vulnerabilities.
