VPN Connectivity

Virtual Private Network (VPN) connectivity is another important feature of UTM firewalls. VPN is a secure network connection that allows remote users or branch offices to access company resources over the internet. VPNs provide a high level of security, privacy, and anonymity for users, as they encrypt communication between the user’s device and the company’s network, thus preventing interception and monitoring by third-party actors.

With UTM firewalls that have VPN capabilities, remote workers can connect securely to the company’s network and access resources as if they were in the office. This is particularly crucial during periods of emergencies or disruptions, such as the COVID-19 pandemic, where many organizations have shifted to remote work to maintain business continuity.

4. Anti-Spam Protection

Anti-spam protection

The standard email account receives many unsolicited and potentially harmful email messages every day, also known as spam. UTM firewalls come with Anti-Spam Protection features that filter out unwanted emails and prevent them from reaching their target. This feature regularly updates its database to keep up with new spamming techniques and techniques used to evade spam filters.

In addition, anti-spam protection helps to reduce the time users spend dealing with unwanted emails, freeing them up to be more productive, and minimizing risks of falling for phishing scams or having their systems exposed to malware.

5. Gateway Antivirus

Gateway Antivirus

Gateway antivirus is an advanced security feature that scans all incoming and outgoing internet traffic for any malicious software, such as viruses, worms, and trojans. This feature works at the network perimeter to protect against external threats that other individual antivirus programs may miss.

Gateway antivirus uses intelligent scanning technology to detect and remove threats in real-time before they reach the network’s endpoints, such as servers or workstations. In case it detects any viruses or malware, it isolates the infected endpoints and notifies the network administrator.

In conclusion, UTM firewalls enhance network security by providing a comprehensive suite of security features.
