Security and clear communication matter. This page lists our official domains, email formats and verified contact methods, so you always know you're talking to our genuine team. A few are pinned around this page.
SISI Solutions (operating under Sevilla Tech Solutions Limited) maintains two primary domains for distinct operational purposes. We only send email from these domains — if a message claims to be from us and doesn't match, treat it as suspicious.
Our primary European headquarters domain — hosts our main corporate website, technical practice insights, and serves as our primary public-facing portal.
Our legacy global domain, now used as our secure corporate communication backbone. Official staff emails and internal application hosting route through this domain.
We will never ask for passwords, sensitive system access keys, or initiate wire
transfers via unsolicited emails or direct messages. If you receive a suspicious communication
claiming to be from us: general or public-facing contact always comes from @sisisolutions.ie;
if you're an active client, staff-level or project communication comes from @sisisolutions.com.
A message that doesn't match either isn't from us.
When in doubt, contact your designated account lead directly, or use the
contact form on our .ie website.
