DNSSubdomains and lookalikes
Every name that points at you, and the ones pretending to.
Old subdomains keep resolving long after the project ends, and a DNS record pointing at a deleted cloud resource is an open invitation for takeover. Nulink enumerates your subdomains, flags dangling records, and watches for newly registered lookalike domains that could be used for phishing.
What it finds
- Forgotten staging, test and campaign subdomains
- Dangling CNAME records at risk of subdomain takeover
- Typosquatted and homoglyph lookalike domains
- Lookalikes with mail servers or live sites configured
How it works
- 01
Enumerate
Nulink builds the full list of subdomains under each domain you own.
- 02
Resolve
Each record is checked to confirm it points at something that still exists and is yours.
- 03
Watch registrations
Newly registered domains are compared with yours to spot impersonation.
- 04
Alert
You're told when a record starts dangling or a lookalike goes live.
What changes for your team
Takeover prevention
Remove dangling records before someone claims the resource behind them.
Earlier phishing warnings
Spot impersonation domains while they're still being set up.
A tidy DNS zone
Retire the names you no longer need.
