Messageware EPG & Spamhaus real-time DNSBLs
Exchange Servers receive thousands of connection attempts each year. While many are legitimate, businesses are often unaware that some originate from virus or malware-infected users, or from malicious actors probing for vulnerabilities. When these connections succeed, they can lead to data exfiltration, or in the worst case, ransomware attacks.
With this seamless integration, gain enhanced control, and ensure email client connections are only from legitimate users, keeping your corporate network and users safe.
Block unauthorized connections
Combining the EPG software with Spamhaus’ leading data ensures only legitimate corporate users can connect.
Proactive Protection
Our datasets protect against malicious threats in real time, including malware, IPs hijacked or compromised by 3rd party exploits, and botnets hijacked or leased for cybercrime.
Stay ahead of malicious activity
A cost-effective, proactive solution that reduces risk and prevents costly down time.
