Ransomware is malicious software, or malware, that encrypts the information on individual devices or even entire networks. It will not release these files until the user pays a fee — or ransom — to unlock them and get them back. Occasionally, even when ransom is paid, the files are not released.
Ransomware has quickly become the most profitable type of malware ever seen. Cybercriminals are making billions a year and the threat is growing exponentially.
Malicious ads that automatically download malware or redirect users to exploit kits while they visit infected websites.
Software kits that identify vulnerabilities so that they can upload and run malicious code, such as ransomware.
Links or attachments in phishing or spam emails infected with ransomware.
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.
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.
Cisco Umbrella blocks requests to access suspicious domains to stop users from visiting websites contaminated with malvertising and other threats.
Sometimes malware disguises its malicious behaviour to pass initial inspection. AMP for Endpoints blocks the file when it shows its true nature.
Cisco Umbrella blocks the downloaded ransomware file from requesting access to Encryption Key Infrastructure
