How to choose

Which threats does it need to block?

Start with the threats you need to address: phishing and malware, web application attacks, DDoS traffic or automated bots.

Compare the listed protection features directly. A web application firewall, or WAF, filters requests to a website or app; DDoS protection addresses traffic intended to overwhelm a service.

Where does the security software need to run?

Choose a deployment that fits your environment, such as a web service, API, Linux system or self-hosted setup.

Platform availability varies. Check the platform marks for the tools you are considering, including web, iOS and macOS support.

How many websites does it need to cover?

Use the websites-covered comparison to check whether a tool fits the scope of your sites.

If you are protecting an API as well as websites, compare API support and the public API mark; they describe different things.

What will the plan cost, and can I try it first?

Compare the free-plan mark with the starting price and billing unit. A per-user monthly price is different from a monthly service price.

A free trial is not the same as a free plan. Check both before choosing, and note that some pricing is available only on request.

Do I need an API or open-source code?

Check for a public API if the tool needs to connect with other software or fit into an existing workflow. The API mark indicates availability, not a specific integration.

If you need to inspect or change the code, check the open-source mark and the tool's licence.

Questions

What does web security software do?

It helps protect websites and apps by blocking threats such as phishing, malware, malicious bots, and attacks on web applications.

What should I compare when choosing web security software?

Compare threat protection, deployment, websites covered, platform support, free plans, starting prices, public APIs and open-source availability.

Is a free trial the same as a free plan?

No. A free trial provides time-limited access, while a free plan is an ongoing no-cost option. Check the plan details before choosing.

What is a web application firewall?

A web application firewall, or WAF, filters requests to a website or app to help block harmful traffic.

Can web security software protect an API?

Some tools list API support. Check the API platform mark and protection details; a public API mark means the tool offers an interface for connecting software.

How much does web security software cost?

Prices vary. Listings can show a free plan, a starting monthly or per-user price, or pricing on request. Compare the stated billing unit.
