OPSSHIELD

OPSSHIELD LLP builds security software for Linux web hosting servers, a venture it says was established in 2016 by a small team of people who had worked for major hosting, support and development companies and have known each other for years. Its best known product is cPGuard, which runs as an agent on a server and is managed from one central portal, so an administrator can watch hundreds of machines from a single place.

A server agent that scans, cleans and blocks

cPGuard combines several protections. A malware scanner watches for file changes and removes injected code from infected files and from the core files of content management systems such as WordPress, so that a site is not taken down by the clean-up. A ModSecurity-based web application firewall carries rules aimed at generic weaknesses in site code, and brute force and bot protection reduces the load that hostile traffic places on a server. A real-time abusive IP database, called IPDB, blocks requests from known bad addresses before they reach the web server, and domain and IP reputation checks are included. The company also sells a lighter edition, cPGuard lite, and a captcha product.

Panels supported and a security-first control panel

Setup is described as quick on the common hosting control panels: cPanel/WHM, DirectAdmin, Plesk, CyberPanel, InterWorx, Control Web Panel, Enhance, RunCloud, Webmin and Webuzo, as well as standalone servers. The newer cPGuard X is a hosting control panel with the security tools built in. It offers a file manager, in-browser editor, MySQL database manager with phpMyAdmin, cron and log tools, automatic SSL certificates, scheduled backups with one-click restore, and one-click site deployment from a single dashboard.

Who uses it, and the November 2026 disclosure

The company says cPGuard is meant for hosting companies running VPS or shared servers and for small businesses that own a server, with or without a control panel. On 3 November 2026 it published a notice disclosing that its cPGuard update channel had been compromised between 1 and 2 November, and that a clean update, version 5.88.26, had been released.
