What is Ransomware?
Ransomware has quickly become the most profitable type of malware ever seen. Hackers encrypt the files in your computer and ask for a fee — or ransom — in exchange for the encryption keys. See how a ransomware attack unfolds.
Adversaries exploit your vulnerabilities
Malvertising
Malicious ads that automatically download malware or redirect users to exploit kits while they visit infected websites.
Exploit kits
Software kits that identify vulnerabilities so that they can upload and run malicious code, such as ransomware.
Email exploit
Links or attachments in phishing or spam emails infected with ransomware.
Poor network security
Ransomware can target entire networks to maximize the impact and profitability of an attack.

There are multiple ways for ransomware to get in. To reduce the risk of infections, organisations need a layered defense. Our ransomware defense solution protects you from the DNS layer to email to the endpoint and it's backed by industry-leading Talos threat research.
First line of defense
Cisco Next-Generation Firewall blocks suspicious connections, while Cisco Advanced Malware Protection (AMP) contains and remediates malware. Cisco Email Security blocks phishing and other email threats used to deliver ransomware payloads.
Block bad websites
Cisco Umbrella blocks requests to access suspicious domains to stop users from visiting websites contaminated with malvertising and other threats.
Retrospective security
Sometimes malware disguises its malicious behaviour to pass initial inspection. AMP for Endpoints blocks the file when it shows its true nature.
Stop encryption
Cisco Umbrella blocks the downloaded ransomware file from requesting access to Encryption Key Infrastructure
