A domain that is only one character different than yours reads as yours. Attackers register these lookalikes cheaply and then start using them to attack your business. They can send invoices from a name your customers might trust, host fake login pages, or impersonate your staff. Alesian Security watches for these domains, then researches them to identify which are actual threats, so that alerts are worth reading. We: - Check that the domain is actually registered and live - Rank the domains based on what they can do: a domain registered last week that can send mail is riskier than the domain that has been parked for years - Track each domain's history, so we know when its digital footprint changes and can raise the risk when one is weaponized - Provide blocking that doesn't wait on a registrar You can explore lookalikes for the 100 most popular domains without logging in, and start watching your own domain for free with no payment information. Pricing is public and per domain. Alesian Security is built by a founder with years in threat research, email fraud prevention, and domain intelligence for the companies that get hurt by lookalikes but can't justify an enterprise brand protection contract.
