Protect Your Mail Servers

We’re the first line of defense for your mail servers which allows you to save bandwidth and CPU caused by the more costly in-depth spam and virus analysis required for later content filtering.

We also protect you from new threats as our traps will see emerging threats early thereby protecting you from new virus and malware strains or new spam and phishing attacks, and we can also help you to identify compromised accounts within your network.

We are always working on new and improved data either from feedback from our customers or where we see new abuse patterns.

We don’t just provide IP addresses and Domain datasets. We also produce hashed datasets for Short URLs, Drive URLs, Bitcoin Wallet address, and email addresses (coming soon).

We also provide non-blocklist datasets like Newly Observed Domains or Newly Observed Mail IPs which can be used for additional filtering and intelligence.

Case Study

Abusix has remained committed to the relationship long after implementation. We have a continued cadence of communication and they are eager to hear customer feedback. As they’ve developed new features, they have also been sure to listen to our team members on what they like and don’t like. The continued customer feedback cycle has led to a stronger vendor relationship than typically seen in the SaaS business.
