What SecurCheck checks
Lookalike domains may support phishing portals or impersonation emails. Review the available evidence before responding or signing in.
- Registration date when published by RDAP
- Current DNS and hosting network
- Public Certificate Transparency observations
- Visible redirects and available threat-list results
What to do when something looks suspicious
Stop interacting with the item, preserve the evidence and contact the person or organisation through a separately verified channel.
A SecurCheck score supports a decision but is not a certification or an absolute guarantee. New, private or unavailable signals may remain unobservable.
Detect typosquatting and targeted phishing infrastructure
A domain imitating your brand, subsidiary or supplier can host a fake sign-in portal or carry convincing phishing messages. A single changed character can mislead employees and expose accounts or payments.
With SecurCheck Business, give IT, support and SOC teams a way to check a suspicious domain. Depending on source availability, the tool brings together RDAP registration dates, current DNS resolution and network context, certificates observed in public logs, visible redirects and available reputation signals. These clues help assess lookalike domains and domain reputation before a decision.
SecurCheck does not query a complete historical DNS database or certify domain ownership or site safety. Sources may be unavailable; confirm sensitive requests through a known contact and follow your incident-response procedures.
