Introduction
Cyber threats are constantly evolving, making it harder for businesses to stay secure. Traditional security measures, like annual penetration tests or compliance audits, are no longer enough. Continuous Threat Exposure Management (CTEM) provides a proactive way for organizations to identify, assess, and fix security risks in real-time.
Instead of waiting for a breach to happen, CTEM helps businesses stay ahead of attackers by continuously monitoring vulnerabilities and minimizing potential attack surfaces. This article breaks down what CTEM is, why it matters, and how businesses can implement it effectively.
What is Continuous Threat Exposure Management (CTEM)?
CTEM is a real-time, always-on security approach that helps organizations find and fix vulnerabilities before they can be exploited. It uses automated scanning, AI-driven analysis, and threat intelligence to keep security teams informed of potential looming security risks.
Unlike traditional security testing, which happens occasionally, CTEM provides continuous insights into a company’s security posture, ensuring threats are detected and addressed as they arise.
How CTEM Differs from Traditional Security Approaches
| Traditional Security | Continuous Threat Exposure Management (CTEM) |
| Conducted periodically (e.g., yearly or quarterly) | Operates continuously in real-time |
| Focuses on known vulnerabilities | Identifies emerging threats |
| Static testing, often manual | Automated, AI-driven risk analysis |
| Requires scheduled updates | Provides ongoing security assessments |
