Managed IT & Cyber Security for Financial Services

Modern financial firms need more than a helpdesk. They need a managed partner who governs Microsoft 365, layers cyber security, maintains tested backups, supports secure remote access for advisers and provides senior strategic input. Reactive break-fix is no longer enough, regulated businesses can’t afford queue-based support, weak controls or undocumented processes when clients, regulators and insurers ask hard questions.

Start with the fundamentals: phishing-resistant MFA on every account, managed EDR on every endpoint, Conditional Access policies, advanced email defence, independent Microsoft 365 backup and security awareness training. Then layer in DLP, identity monitoring, Cyber Essentials alignment and a documented incident response plan. The goal is a defensible, evidenced baseline that protects clients and stands up to insurer and regulator scrutiny.

Microsoft 365 holds your client correspondence, KYC documents, contracts, financial data and internal IP, making it the highest-value target in your business. Default tenant settings are not secure or audit-ready: legacy authentication is often enabled, SharePoint is over-shared, guest access is uncontrolled and there is no third-party backup. A properly governed tenant with MFA, Conditional Access, retention, DLP and independent backup dramatically reduces the risk of email compromise, payment fraud and data loss.

Look for a UK-based managed partner with genuine sector experience, named senior engineers, predictable response SLAs, mature Microsoft 365 expertise, integrated cyber security and a clear strategic review cadence. Avoid providers who are reactive, sell security as a separate upsell, or can’t evidence their own controls. Your IT partner becomes part of your operational and regulatory posture, choose them accordingly.

Our average response time is under 11 minutes, with a target of under 30 minutes across all support channels. 98% of issues are resolved on first contact by our UK-based engineers, and the majority are handled remotely without an adviser ever needing to leave their desk. Critical incidents, including suspected breaches and major outages, are escalated immediately under documented major-incident procedures.

Operational resilience for a financial firm means more than a backup file. It means independent, immutable backup of Microsoft 365 and on-prem systems, rehearsed recovery scenarios, redundant connectivity, secure device management and a clear plan for what happens if the office or a key system is unavailable. ATS builds and tests this as part of the managed service so leadership can answer continuity questions from clients, auditors and regulators with confidence.
