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.
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:
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.
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.
