Best Website Security Software

Kinsta is a managed WordPress hosting platform built on Google Cloud infrastructure, and security is bundled into every plan rather than sold separately. Each site runs in its own isolated container, backed by a Cloudflare-powered web application firewall, DDoS protection, and automatic bot blocking. Kinsta issues free SSL certificates with automatic renewal, bans IPs after repeated failed logins, and runs continuous uptime and malware monitoring across its network.

Every plan includes a hack-fix guarantee, meaning Kinsta's security engineers clean up a compromised site at no extra charge. Daily automated backups keep full-site snapshots for quick restoration. The underlying infrastructure holds SOC 2 Type II and ISO 27001 certifications, making Kinsta a common choice for agencies and businesses that want enterprise-grade WordPress security without managing it themselves.

MalCare is a WordPress security plugin that scans sites for malware using AI-based detection, then removes infections with a one-click cleanup process designed to avoid breaking the site. It also includes a real-time web application firewall, bot protection, login security, vulnerability alerts for outdated plugins and themes, and site backups.

Plans scale from a free tier with weekly scans up to the Fortify plan built for high-traffic WooCommerce stores with hourly scanning and a six-hour expert response time. MalCare is developed by BlogVault and is aimed at individual site owners, freelancers, and agencies managing multiple WordPress sites.

Solid Security began as Better WP Security, was later renamed iThemes Security, and became Solid Security under the SolidWP brand. It was a WordPress plugin offering brute-force protection, two-factor authentication, password enforcement rules, file change detection, and Patchstack-powered vulnerability alerts and virtual patching. In May 2026, Liquid Web consolidated the SolidWP brand into its Kadence WordPress product line, and the plugin was renamed Kadence Security.

Kadence Security is no longer sold as a standalone product. It now ships only inside the paid Kadence Pro and Elite site-builder bundles, alongside backups and multi-site management tools, though a limited free hardening version remains on WordPress.org. Buyers who want just the security features must now purchase the full Kadence suite, and critical security patches for the retired standalone product are only guaranteed through April 2027.

Astra Security provides a continuous penetration testing platform that combines an automated vulnerability scanner running thousands of tests with manual testing from certified security experts. Results feed into a single dashboard with compliance-ready reports for standards like SOC 2, ISO 27001, HIPAA, and PCI, plus AI-assisted remediation guidance.

Astra sells its pentest product in two main yearly tiers plus a custom Enterprise option, and separately offers a website protection product (firewall and malware scanner) under its WebPro/webprotect.ai brand. The company is legally based in the United States and serves startups through large enterprises needing recurring security testing.
