Paying is not a guarantee that your computer or network will be unlocked. It is better to protect your systems and with measures that help prevent infection.
Large Businesses - a multi-point approach is best
- Email and Web protection - block spam and access to malicious links.
- Server protection - protect servers from exploitable vulnerabilities.
- Network protection - prevent ransomware from spreading to endpoint.
- Endpoint protection - prevent ransomware from running on endpoint.
Small Businesses - a two-point approach is effective
- Email protection and Web - block spam and access to malicious links.
- Endpoint protection - block access to malicious/ compromised sites and prevent ransomware from running.
Home User - one step provides necessary protection
- Use a security solution that stops spam, prevents access to malicious links and stops infection.
