Corporate email

Service permissions

I have read how XRENN Labs s.r.o. processes my contact details, account information and security findings to provide the requested service. Security & Privacy I own the domain derived from my corporate email or am authorized by its owner to permit public-source lookups and limited DNS, TLS, HTTP and TCP checks, including permission from affected hosting providers. I authorize XRENN Labs s.r.o. to perform these checks. Optionally, enable repeated monitoring at the interval shown in my portal. I can revoke this authorization there at any time.

No exploitation, password attacks or denial of service. A penetration test requires a separate written scope and authorization. The scan starts only after email verification.
