Network security is essential aspect for your business environment!
Firewalls are generally used to prevent unauthorised Internet users from accessing private networks connected to the Internet. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
Every company network needs a firewall to protect confidential information and internal systems from those not authorised to access it and to protect against malicious users and accidents that originate outside your network.
One of the most important elements of a firewall is its access control features, which distinguish between good and bad traffic.
