IT Support & AI Solutions Across London

London is one of the world's great business cities, but for small businesses with 1 to 50 staff, getting reliable, affordable IT support can be a challenge. Large MSPs often treat smaller clients as an afterthought, while freelance IT contractors can be unreliable when you need them most.

Senri fills that gap. We provide managed IT support, Microsoft 365 security, cybersecurity, and AI-powered automation for small businesses across London and Greater London. From the City to West London, we give growing businesses access to the same enterprise-grade tools, Microsoft Defender, Intune, Purview, Conditional Access, that protect FTSE 100 companies, configured for smaller teams at a fraction of the cost.

Our managed IT support covers everything a small London business needs. Day-to-day helpdesk support via phone, email, or Teams. Device management with Intune, every laptop encrypted, managed, and remotely wipeable. Microsoft 365 administration including user accounts, licences, security policies, and email configuration. Onboarding new starters with fully configured devices on day one. Offboarding leavers with access revoked immediately. Proactive monitoring that catches problems before your team notices them.

For London businesses concerned about cybersecurity, we take a practical approach based on what actually stops attacks. MFA on every account blocks 99.9% of automated credential attacks. Conditional Access policies restrict sign-ins to trusted locations and compliant devices. Anti-phishing policies in Microsoft Defender catch spoofed emails and malicious links. Email authentication (SPF, DKIM, DMARC) prevents attackers from sending emails as your domain. And proper backup strategies, real backup with tested recovery, not just OneDrive sync, protect against ransomware and data loss.

AI automation is where many London businesses see the biggest impact on their bottom line. We build custom workflows that automate repetitive tasks: lead follow-up, invoice chasing, proposal generation, report creation, data entry between systems, and client communications. These connect to the tools you already use, CRM, accounting software, email, messaging platforms, and run in the background. A typical workflow saves 5-10 hours per week and pays for itself within the first month.

Based in Brentford, West London, we serve clients across the capital with a response time consistently under 30 minutes. No long-term contracts, no jargon, and a real person who picks up the phone when you need help.
