Netcraft provides threat data and takedown services to organizations around the world, but our tools aren’t just for enterprise.

We offer a set of free apps and browser extensions that help anyone block malicious sites and report new threats. They’re straightforward, lightweight, and built on the same intelligence we use to protect our customers.

They’re also part of a broader effort: making it easier for individuals to protect themselves—and contribute to a safer web in the process.

Powerful Tools, No Subscription (or Cost) Required

Our apps and browser extensions block malicious websites using the same threat intelligence we provide to enterprise customers. The difference? You don’t need a license to use them.

You get:

·      Real-time protection against phishing, credential skimmers, fake shops, crypto miners, and more

·      Reporting tools to flag suspicious URLs (you can even win prizes for it)

·      Detailed site reports that reveal hosting location, ownership, first seen date, and more

All of this is backed by Netcraft’s world-class threat feed—the same one licensed by browser vendors and relied on by global security teams.

Mobile Protection for Android and iOS

Stay safe online — wherever you go. Netcraft’s mobile apps bring powerful threat protection to your device, whether you use Android or iOS.

On Both Platforms

Our apps for Android and iOS block access to known malicious sites using the full Netcraft threat feed. You'll benefit from:

• Real-time protection in major browsers and apps (including Chrome, Firefox, and Safari)

• Continuous updates from our extensive intelligence network

• Clear stats on which threats are blocked

• The ability to report suspicious content directly

iOS: Extra Privacy and Advanced Tools

In addition to core protections, the iOS app offers extra capabilities thanks to Apple’s content blocking framework and device integrations:

• Enhanced privacy (we never see your browsing data)

• Curated list of ~300,000 threats, refreshed regularly

• QR code scanner that checks links before you open them

• SMS auto-reporting for suspicious messages from unknown senders

• Siri Shortcuts for quick safety checks and advanced automation:

  • “Is this site safe?”

  • “When did Netcraft first detect this domain?”

  • “Where is this site hosted?”
