What we do

Your security team’s early warning. Ranked for you.

Every day, thousands of new security problems are found and criminals start using some of them. We keep track of all of it, work out which ones affect you, and tell you exactly what to do.

1 · We watch

Everything, continuously

We keep an eye on the whole internet and your corner of it, so you don’t have to.

  • New security flaws as they’re found
  • What criminals are actively using
  • Your domains and certificates
  • Fake sites copying your brand
2 · We work out what matters

Only what affects you

We match it all against your business and rank each issue by how likely it is to actually be used against you.

  • Ignores the noise that doesn’t apply
  • Puts real, active threats first
  • Shows the reason behind every ranking
3 · We tell you what to do

A short list, with the fix

You get a clear to-do list, step-by-step fixes and an alert as soon as we spot something urgent that affects you.

  • Fix steps written for your team
  • Alerts by email, in the app or to your tools
  • Reports you can share with the board
Less time wastedStop chasing hundreds of alerts. Work on the handful that matter.
Fewer surprisesHear about a threat before it reaches you, not after.
Protect your customersSpot fake websites and scam emails using your name, early.
Prove you’re on top of itClear reports for your board, insurers and customers.
Prioritisation

Not every problem is urgent. We show you which ones are.

Most security tools rank problems by how bad they could be in theory. That buries the one criminals are using today under dozens that will never be touched. We rank by how likely each problem is to actually happen to you.

Try it on the right. Sorted the usual way, the problem that’s under attack right now is fourth on the list. Sorted by Precursor Intelligence, it’s first, with the reason beside it.

Coverage

Every way in, watched in one place.

Attackers don’t just use one route. Precursor Intelligence covers all of them and puts everything into one ranked list, so you’re never comparing apples with oranges.

Know which software flaws actually matter

Tell us the software your business runs. Whenever a new flaw is found in it, we score it from 0 to 100 on how likely it is to be used against you, and give you the fix.

It keeps watch over your business online: the software you run, everything of yours that can be reached from the internet, and lookalike websites using your name. It ranks what it finds by how risky each issue is, starting with what criminals are already using, and tells you what to fix first and how.

No. It runs in your web browser. We work from public internet data, the software you tell us you use and any files you choose to upload, so there’s nothing to install on your computers or network.

You either pick it from our catalogue or let us work it out from your public website. We then match known flaws against those products, so you only see what affects you.

We monitor continuously for newly published flaws, flaws that criminals have started using and flaws that are becoming more likely to be used, in the software you track. As soon as we spot something that affects you, it arrives by email, in the app or in your own tools by webhook.

Yes. Your organisation owns the account and its data, and there’s no limit on how many colleagues you invite.

Your data is stored in London, and each organisation’s data is kept separate from everyone else’s. Everyone signs in with two-factor authentication, keys for the tools you connect are encrypted, and API secrets are never stored, only a fingerprint of them.
