The Net Fix for business
Find and fix the gaps attackers look for. Keep every office online.
Four free security checks for your domain, website and office network, each with the exact fix, plus network checks that find where office lag starts.
Security checks, free
No sign-up. Each gives an A–F grade or a clear verdict and a ranked list of fixes. They find common exposures; they aren't a penetration test, and no tool keeps you safe from every attack.
Email security check
Checks SPF, DMARC, DKIM, MTA-STS, TLS-RPT and BIMI, grades how easily your domain can be forged in phishing emails, and gives the exact records to publish.
Check my email domainWebsite security check
Grades HTTPS, HSTS, Content-Security-Policy, clickjacking protection, cookie flags, version leaks, DNSSEC and CAA, with the header or record for each fix.
Check my websiteLookalike domain finder
Generates typo and look-alike versions of your domain and shows which are registered and which can send email, the raw material of invoice fraud.
Find look-alikesExternal exposure scan
From the internet, tries the services attackers scan for (RDP, SMB, databases, admin panels) on the network you're on, and says how to close each one.
Scan this networkNetwork tools for offices
Lower lag on calls and find where bottlenecks start: in the office, on the line or at the provider.
Open port checker
Checks whether one port you choose answers from the internet, for example after setting up a VPN or a forward.
Check a portIs it down or is it us?
Checks Slack, Zoom and other services' status pages against your own connection, so you know whose problem it is.
Check what's downFree for offices too
- Your company domain's email, website and look-alike checks in one click with Test & Optimize
- Open-port exposure scan of the office line, with what to close first
- Lag under load, Wi-Fi and call-readiness checks for every desk
- No IP addresses, domains or results stored
Nothing kept from the checks
Domains you check, your address and the results are used for that one request and never stored or logged.
Plain fixes
Every finding says why it matters and gives the exact DNS record, header or setting to change, in the order to do them.
Honest about limits
We say what each check can't see. The Net Fix lowers lag by finding bottlenecks; it can't make a line faster than the plan you pay for.
