Stop Ransomware

Stop threats and reduce business risk with a proactive zero trust security architecture

Zero trust powers the world’s most effective ransomware protection

Ransomware attacks are making more headlines every day. Cybercriminals are launching more sophisticated attacks, ransom payments keep growing, and no industry is off-limits. Protecting your important files and data in today's evolving ransomware landscape requires a more effective approach—so defenders are looking for new solutions.

ransomware infections include data theft, forcing victims to pay up to prevent data leakage—also known as double extortion.
Every ransomware incident is now a data breach
Threat actors are stealing sensitive data to increase the pressure on their victims to pay ransoms.

security risk is lateral movement within corporate networks.
The corporate network is your biggest risk
Legacy hub-and-spoke networks and "next-gen" firewalls leave your enterprise open for ransomware attacks to move laterally.

Ransomware attacks require proactive defenses

Zscaler provides ransomware protection to disrupt every stage of the ransomware attack life cycle in ways legacy antivirus and other security tools can’t.

Ransomware attack life cycle

Today’s cyberattackers use sophisticated tactics to bypass conventional ransomware detection and hide in trusted and encrypted traffic. They move through the network and steal data, threatening to publish it if victims don’t pay. Once they have what they need, they execute the ransomware, encrypting data and wreaking havoc.

Legacy security architectures fail to stop ransomware

“Next-generation” firewall functionality and security point solutions introduce blind spots, complexity, and high costs—all resulting in significant risk. These legacy approaches make it cost-prohibitive to inspect encrypted files and traffic, allowing attackers hidden within to move laterally and infect other systems.

Stop ransomware at every stage of the attack life cycle

The Zscaler Zero Trust Exchange™ prevents attackers from discovering, exploiting, or infecting users and apps by making those users and apps invisible, accessible only to authorized users or devices. It inspects all inbound and outbound traffic inline, encrypted or not. Authenticated users and devices connect directly to the applications they need, never to the network—so even if an attacker gets in, they can't move laterally to steal or encrypt data.
