About Daystar

Daystar reviews paint a consistent picture: a 5.0 Google rating across 24 ratings, with customers like the Centennial Hotel calling out engineers by name and crediting fast, friendly fixes. Reviewers highlight the team's response time and depth of talent, with one long-term client noting Daystar breaks down IT security needs in clear budget language and has caught phishing attempts that would otherwise have landed. Susan Saucier sums up the theme, thanking the team for always being there.

Operating from Newington and serving Portsmouth, Daystar runs managed IT services, managed detection and response, and co-managed IT for healthcare, pharma and med-tech, manufacturing, government, and finance clients across the Seacoast. ITAR-aligned work and vCIO planning sit alongside the day-to-day help desk, so a regulated employer gets both compliance depth and routine support from one team.

The service mix spans cybersecurity, cloud migration, and backup and disaster recovery, all delivered as a proactive monthly program rather than reactive call-outs. For a defense supplier or clinic that needs IT managed and secured to an audit standard, Daystar's verified record and personal attention make it a credible shortlist candidate.
