What Does Your Cybersecurity Rating Actually Mean — And How Is It Calculated?

Millions of organizations now have a public A–F grade. Here's exactly what drives that score, how attackers use it against you, and what you can do to improve it in 30 days.

If you've ever googled your company's name and seen a letter grade next to it — A, B, C, D, or F — you've encountered a cybersecurity rating. These ratings are generated continuously by security intelligence platforms and are publicly visible to anyone, including your customers, partners, and adversaries. Yet most executives don't understand what moves the score or why it matters.

The 6 Scoring Dimensions

Cybersecurity ratings aggregate signals from dozens of external, non-intrusive sources. No system access is required — everything is observable from outside your network. Scores are typically broken down across these key dimensions:

Email Security (up to 30 pts)
DMARC, DKIM, and SPF configuration. Missing or misconfigured email authentication is the single most common cause of a failing grade.
SSL/TLS Configuration (up to 20 pts)
Certificate validity, cipher suite strength, and TLS version support. TLS 1.0 and 1.1 are deprecated and heavily penalized.
Known Vulnerabilities (up to 25 pts)
Open ports running outdated software with known CVEs. Each unpatched critical CVE can cost 5–10 points.
Dark Web Exposure (up to 15 pts)
Compromised credentials and sensitive data appearing on criminal forums and paste sites tied to your domain.
Network Security (up to 10 pts)
Open management ports, exposed admin interfaces, and insecure DNS configurations.

Why Your Grade Changes Without Warning

Scores are recalculated continuously — often daily. A certificate that expires, a new CVE published against software you're running, or a batch of your employees' credentials appearing on the dark web can drop your score by 10–20 points overnight. This is why ongoing monitoring, not just a one-time assessment, is critical.

How Attackers Use Your Rating

Threat actors actively query cybersecurity rating APIs to prioritize targets. Organizations with D or F ratings are statistically 4x more likely to experience a successful breach — because a low rating signals that basic hygiene controls are missing, making initial exploitation easier and faster.

How to Improve Your Grade in 30 Days

  1. 1.Configure DMARC enforcement. Set your DMARC policy to p=quarantine or p=reject. This alone can recover 15–20 points.
  2. 2.Renew and audit all SSL certificates. Expired or self-signed certs are an immediate penalty.
  3. 3.Disable TLS 1.0 and 1.1. Enforce TLS 1.2 as the minimum, TLS 1.3 where possible.
  4. 4.Close unnecessary open ports. Audit firewall rules and remove internet-exposed services that don't need to be public.
  5. 5.Scan dark web exposure. Reset compromised credentials immediately and enable MFA across all accounts.
