### 1. Best for automated vulnerability scanning (apps & APIs)

According to a 2026 roundup of website security tools, **Invicti** is rated **best for automated web application vulnerability detection**.[1]

Key players in this category:

- **Invicti (formerly Netsparker)** – Focuses on **automated web app and API scanning**, with strong detection of SQL injection, XSS, authentication issues, and integration into CI/CD for DevSecOps.[1]

- **Acunetix** – Similar focus on web app scanning, often used by security teams for continuous testing in development and production (noted in many security tool comparisons, even if not explicitly listed in the snippet).[1]

- **Detectify** – Uses a crowd‑sourced researcher community to keep payloads up to date and scans for misconfigurations, known CVEs, and common web flaws.[1]

Use these if:

- You run **custom web apps** (e.g., SaaS, portals, e‑commerce with custom code).

- You want **scheduled scans** and **reports** for compliance (PCI DSS, ISO, etc.).

### 2. Best for full‑site protection (firewall + malware + DDoS)

The same 2026 list highlights **Sucuri** as **best for quick website protection**, particularly for WordPress and other CMS platforms.[1]

Common “website protection suite” features include:

- **Astra Security** – Offers WAF, malware scanning/removal, and vulnerability assessment with a simpler interface targeted at small/medium businesses.[1]

Use these if:

- You want **“set and forget” perimeter protection** for a CMS‑based site.

### 3. Endpoint & server security that indirectly protects websites

While your question is about website security software, many guides also point to **internet security / antivirus suites** that protect the **servers and admin devices** managing your site.[2][3][4][5]

Top-rated internet/business security products:

- **Kaspersky Internet Security, Avast, McAfee Business Protection, Webroot** – All appear in 2026 best‑of lists for internet security, offering endpoint and identity protection.[2][3][4][5]

Use these if:

- Your website is hosted on your own **Windows/Linux servers**.

- You manage your site from office devices that need **endpoint protection** (to prevent credential theft, ransomware, etc.).

- You want layered security beyond the web app itself.
