Are You Proactive? The Difference Between Reactive and Proactive Cybersecurity
Most organizations know they have a cybersecurity problem. Far fewer have built a program that addresses threats before they materialize into incidents. Here is what proactive security actually looks like.
By Tom Brennan
The difference between reactive and proactive security is the difference between responding to fires and building fireproof structures.
What Reactive Security Looks Like
Reactive organizations have security tools deployed, but they are primarily configured to detect and alert. Incident response plans exist but have not been tested recently. Patches are applied after vulnerabilities are publicized. The security team spends most of its time responding to alerts rather than hunting for threats that have not triggered alerts yet.
What Proactive Security Looks Like
- Continuous threat hunting — actively searching for indicators of compromise that have not triggered automated alerts
- Adversarial testing — regularly using CATSCAN® penetration testing to find exploitable vulnerabilities before attackers do
- Risk-prioritized patching — using threat intelligence to prioritize patches based on active exploitation
- Supply chain monitoring — continuously assessing vendor security posture
- Tabletop exercises — regularly testing incident response through simulation
