Cyber insurance is often seen as a safety net that only appears after a fall. With Coalition’s Active Insurance, we do not just wait for a claim; our technology and dedicated security team proactively monitor the digital world. When a threat emerges, Coalition does not just send an automated alert to policyholders — we pick up the phone.

Active Insurance in Action: Vulnerability ‘React2Shell’
In late 2025, a potentially massively damaging vulnerability named “React2Shell” (CVE-2025-55182) was identified. This was a serious, widespread flaw affecting React and Next.js server that could allow an attacker to remotely compromise a machine without a login.

Here is how Coalition’s Active Insurance response protected our policyholders in real-time:
• NOV. 29
A researcher identified a critical, widespread vulnerability impacting React and Next.js applications.
• DEC. 3
The vulnerability was publicly disclosed. Coalition’s security team immediately analyzed exploit chains and rapidly identified every policyholder with vulnerable Next.js assets.
• DEC. 4
Coalition alerted hundreds of businesses via email within hours. Our security analysts followed up with direct phone calls, guiding vulnerable policyholders through mitigation steps and rescanning networks to confirm patching.
• DEC. 5
CISA added React2Shell to its Known Exploited Vulnerabilities catalog.
THE OUTCOME
Coalition successfully identified, notified and contacted hundreds of vulnerable policyholders within 48 hours of the vulnerability’s public disclosure — securing their businesses before attackers could exploit this vulnerability.
