Cyber attacks are on the rise, and the financial impact of a security attack is increasingly costly. With the average cost of a data breach over $3.8 million in 2020, companies look for effective protection.
Almost every organization has a firewall, anti-malware, or endpoint protection tool. Yet, no protection method is perfect and some packets can sneak in past firewalls. Therefore, there is a need to complement the firewall’s limitations.
Also, these methods cannot do much once an attacker is inside the network.
Even with perfect firewall rules, you are going to let some packet in that you didn’t expect. Thus, once traffic comes to your network past a firewall, you need to track it to make sure it isn’t malicious.
Intrusion detection and intrusion prevention tools can solve these challenges.
