An exact-match domain for the consumer and SMB VPN market. Where SEO and brand clarity matter more than abstract positioning — this domain removes all naming ambiguity and communicates the product benefit before a visitor reads a word of copy.

Buying Guide: Cybersecurity Domains

Cybersecurity buyers are the most scrutinising audience in B2B tech. Your domain is a trust signal evaluated before any demo, meeting, or proposal. These names are built to pass that first filter.

The stellar naming convention in security

Constellation and star names (Altair, Sirius, Lyra, Vega, Orion) have become the dominant naming convention in enterprise cybersecurity. The association is precision, constancy, and scale — qualities that directly mirror what security buyers need to feel when evaluating a vendor. Combined with a security-specific second word (Vault, Cipher, Sentinel, Secure), these names create an immediately credible brand architecture.
