Perimeter Security

Digital Metalla’s perimeter security service is a set of devices, protocols, and practices designed to protect the boundary of a network from external threats.



The firewall is one of the main components of a perimeter security system. It filters network traffic based on predefined rules, blocking or allowing packet passage based on criteria such as IP addresses, ports, and protocols.

Gateway antivirus

The gateway antivirus is designed to detect and block viruses, malware, and other threats before they can penetrate the network. It examines incoming traffic and scans files for harmful content.

Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS)

This system monitors network traffic to detect any anomalous behaviors or ongoing attacks. IDSs report potential threats, while IPSs intervene with automatic procedures to block or mitigate attacks.

Web content filtering

This component filters and controls web content based on predefined policies. It can prevent access to malicious websites or restrict access to certain types of content.

VPN (Virtual Private Network)

A VPN allows the creation of encrypted tunnels through a public network, providing secure and private connections for remote users or branches. This helps protect communication between distant locations.

Access control

Implements access control policies to ensure that only authorized users can access specific resources. This may include the use of multi-factor authentication and user privilege management.

Email Protection

Block unwanted and spam emails. Detect any malicious attachments or links that may contain viruses, malware, or other cyber threats. Address phishing attempts to protect users from various types of fraud.

Network device protection (router, switch, etc.)

Configure and protect network devices to prevent unauthorized access and guard against vulnerabilities through firmware updates, traffic filtering, and monitoring, as well as robust authentication methods (cryptographic keys or digital certificates).
