Perimeter 81 Review (2023): Pricing, Pros, and Cons

Perimeter 81 is a cloud-based network security solution designed to help organizations protect their resources using software-defined edge networking, authentication and access control capabilities.

Unlike the typical virtual private network approach to network security, which assumes the user is “safe” once connected to the network, Perimeter 81 adopts the zero-trust network access strategy that combines identity-based access rules, multi-factor authentication, traffic encryption and monitoring to ensure authentication and authorization for each user and device before granting them access to resources. Here is a deep-dive look into Perimeter 81.

Key features

Summarized below are key features you may find interesting in Perimeter 81.

Malware protection

Perimeter 81 offers protection against various types of malware, including trojans, rootkits, viruses, and zero-day exploits. The tool scans web traffic for abnormal behavior and blocks malicious files on your network. It also features a multi-layered detection system, including a database of malware signatures, emulation, heuristics – an algorithmic analysis to detect unusual patterns and behaviors of malware (both hidden and unknown), and machine learning, which is used to detect complex threats such as APTs (advanced persistent threats), ransomware and zero-day attacks.

Web Filtering

Another noteworthy security component of Perimeter 81 is its secure web gateway web filtering capability which allows users to track employees’ web activity, control internet access and block exposure to suspicious sites. This feature allows users to create a web filtering rule that only allows URLs from specific sites – users can determine which sites are “Blocked,” “Warned,” or “Allowed” for different employees and employee roles. Perimeter 81 also provides exportable reports of employees’ web activities for analysis and auditing (Figure A).

Software-defined perimeter

Perimeter 81 uses its software-defined perimeter capability to make an invincible network for a user or device. This method minimizes threats by giving only authorized users access to data or certain information. SDP gateway can be automatically deployed anywhere, enabling simplified, secure, low-latency connections to resources. It also enables encrypted traffic tunnels, which create one-to-one network connections between users.

Monitoring dashboard

The monitoring dashboard allows users to see and track everything on their network. The dashboard consolidates network usage data into a single view, allowing users to see current active sessions, gateways, apps and licenses in use (Figure B).

Zero-trust security

Perimeter 81 operates on a zero-trust framework, meaning that it doesn’t automatically grant access to any user or device, even if they are within the corporate network. Every user and device gets authenticated and authorized before being granted access to resources.
