How do I monitor my organization on the Internet?

Your credentials may leak on the darkweb, your brand may be impersonated for phishing, one of your executives may be targeted. The question isn't if, but when you'll know. This page explains how to see before the attack.

The answers

Four questions, four precise answers

What's the difference between OSINT, deep web and darkweb?

OSINT (Open Source Intelligence) is the visible layer: public sites, GitHub, social networks. The deep web is 96% of the Internet — pages not indexed by Google: exposed intranets, misconfigured cloud shares, private archives. The darkweb is a fraction of the deep web requiring Tor / I2P: criminal marketplaces, ransomware leak sites, hacktivist forums. SYLink covers all three layers continuously.

How do I know if my credentials have leaked?

Without active monitoring, you'll only know once they're exploited. SYLink Leaks checks daily for your credentials in public dumps (HIBP, Collection #1-5), private and recent ones (RaaS, brokers). 12 modules in Basic, 28 in Enterprise, 58 in VIP — every alert is qualified by a French analyst before notification.

Why a sovereign CTI rather than a free feed?

A free OSINT feed gives unqualified noise. SYLink CTI adds three things: (1) quality — deduplication, scoring by real exploitability; (2) velocity — propagation < 2 min to your firewalls and EDR; (3) sovereignty — code, datacenter, teams in France. 12 years of expertise, 30 PB of streams analyzed / month, 3 M attacks blocked / month.

What to do when a leak is detected?

Three steps: (1) contain — forced reset of the leaked account, hardened MFA, endpoint isolation; (2) investigate — correlation with your 5-year DPI storage to reconstruct the chain; (3) prevent — automatic IOC dissemination to all your probes to block the next occurrence.
