PerfectMail Antispam
PerfectMail
PerfectMail delivers better than 99% filter accuracy with false positives (wanted e-mail blocked as spam) at less than 0.1%. PerfectMail automatically learns about your users and their regular e-mail peers and never blocks their e-mail. The only time PerfectMail might have an issue is with a questionable e-mail from new senders. This takes the risk out of antispam filtering. Most spam filters work like this: receive e-mail, queue, filter, deliver or send a non-delivery reply. The problem with this model is that mail is delayed and senders/recipients may never realize that wanted messages were blocked. PerfectMail works in real-time meaning that it filters messages as they are received - without queuing. This means that PerfectMail tells the sender if their message is being blocked. - PerfectMail's antispam engine is programmed C - the fastest programming language in the world.Starting Price: $499 one-time payment -

Active Wall
Active Network CO
Active Wall uses the middle layer drivers developed independently as the filter engines, which are more low-leveled than other software which uses WinPCap. Because WinPCap is a protocol-type driver, it can only monitor but not block. The other software which uses WinPCap can only block TCP communications, but cannot block UDP, ICMP, IGMP data packets. It has been proved that Active Wall is more stable, correct and effective after working online for a long time. Most similar software support the only one mode- Passby monitoring mode. Besides the Passby mode, Active Wall supports more modes including Gateway mode, Bridge mode and Single mode. It is recommended that the users should use the Gateway mode or the Bridge mode. When using the Passby mode, Active Wall can only block TCP data packets for the limit of the network topology. However, the Gateway mode or the Bridge mode enables the Active Wall to block all kinds of data packets.Starting Price: $10 per user -

XM Cyber
XM Cyber
Networks change constantly and that creates problems for IT and security operations. Gaps open exposing pathways that attackers can exploit. While enterprise security controls like firewalls, intrusion prevention, vulnerability management and endpoint tools attempt to secure your network, breaches are still possible. The last line of defense must include constant analysis of daily exposures caused by exploitable vulnerabilities, common configuration mistakes, mismanaged credentials and legitimate user activity that exposes systems to risk of attack. Why are hackers still successful despite significant investments in security controls? Several factors make securing your network difficult, mostly because of overwhelming alerts, never-ending software updates and patches, and numerous vulnerability notifications. Those responsible for security must research and evaluate piles of data without context. Risk reduction is almost impossible. -
