Dark web monitoring: are your staff logins already for sale?
You don’t have to be breached to be exposed. When a third party leaks its user database, credentials go up for sale — and nobody sends you a notification.
When a service your staff use gets breached, the credentials end up on criminal markets. If anyone on your team reused that password at work, your business is now in someone’s list.
Attackers don’t break in. They log in.
With real credentials, through the front door, looking exactly like a legitimate user. That’s what makes it so hard to spot and so effective. From there it’s your email, your invoices and your banking details — and the invoice-redirection scams that cost Australian businesses the most money almost always start with a login somebody else already owned.
The ASD’s Annual Cyber Threat Report 2024–25 found that 42% of critical incidents involved compromised credentials.
What monitoring actually does
- Watches the marketsContinuous monitoring for your company domains and staff email addresses across breach dumps and criminal forums.
- Tells you earlyAn alert when a credential surfaces, so you can force a reset before it’s used against you.
- Closes the gapMFA, password policy and endpoint protection, so the next leak somewhere else doesn’t become your problem.
What we check
- Your company domains
- Staff email addresses
- The accounts most likely to be targeted — finance, payroll and anyone with authority to move money
When something appears, you hear about it from us rather than from your bank.
Why alerts alone aren’t enough
Alerts nobody reads aren’t security. Monitoring is only useful if it comes with a recommended action and someone to call. Paired with Bitdefender GravityZone — which Comstel deploys and manages — monitoring becomes prevention rather than just bad news arriving slightly earlier.
What to do today, for free
- Turn on multi-factor authentication everywhere it’s available, starting with email and banking
- Stop password reuse between work and personal accounts — a password manager makes this realistic
- Make sure finance staff verify any change to payment details by phone, on a number they already had
