Cisco Ransomware Defense

Outmaneuver the cleverest ransomware attacks

Ransomware penetrates organizations in multiple ways, so fighting it requires more than one product. Cisco Ransomware Defense products provide ransomware protection from the DNS layer to email to the endpoint. And our solution is backed by industry-leading Talos threat research.

Evolving ransomware protection needs

Cisco can help with ransomware protection. Our in-depth architectural approach defends users both inside and outside the network.

Ransomware is the most profitable type of malware in history. In the past, attackers primarily tried to steal information and maintain long-term access to their victims’ systems and resources. They typically did not deny access to systems or destroy data. Ransomware has changed the game from stealthy access to extortion.

In a ransomware attack, victims pay attackers directly to recover their files. The emergence of anonymous currencies such as Bitcoin and Ripple has meant that attackers can profit easily and with relatively low risk. This makes attacks highly lucrative and funds development of the next generation of ransomware. As a result, ransomware is evolving at an alarming rate.

Quick prevention

Ransomware protection begins with preventing critical threats. Our ransomware defense solution fights threats on multiple fronts. Get started with quick prevention and add advanced protection when ready.

Endpoint ransomware protection

Cisco Advanced Malware Protection for Endpoints stops ransomware files from taking your system hostage. While you can’t completely prevent risky cyberbehavior, you can enhance the security of your endpoints and servers.

Email ransomware protection

Cisco Cloud Email Security with Advanced Malware Protection (AMP) blocks ransomware delivered through spam and phishing emails. It even identifies malicious attachments and URLs. Email is still the application that ransomware uses most commonly.

Web ransomware protection

Most ransomware attacks use DNS. Cisco Umbrella with DNS and IP layer enforcement stops ransomware over all ports and protocols. Stay protected with Umbrella whether you are on or off the network.
