Book a security assessment

We'll review your systems and accounts, then agree scope and response rules with you before anything is switched on.

This field is for validation purposes and should be left unchanged.

We use your details only to arrange your assessment.

Managed IT and AI Cybersecurity

Managed IT covers proactive support and monitoring, patching, network, cloud and Microsoft 365, backup and disaster recovery, and IT strategy and consulting. Cybersecurity adds analysts who watch connected systems 24/7 and investigate threats within rules a client approves. A client can choose managed IT, cybersecurity or both, fully managed or alongside an in-house team.

AI on both sides of security

FunctionOne uses AI to help analysts spot threats and protects your company from attacks that use AI.

AI working for you

  • Behavior analyticsSoftware learns typical user and system activity and highlights changes such as unusual account behavior.
  • Threat intelligenceInformation about malicious addresses, domains and attack methods adds context when analysts investigate.

Defense against AI attacks

  • Phishing email monitoringAttackers use AI to write convincing phishing emails, so analysts watch Microsoft 365 for unusual sign-ins and forwarding rules.
  • Payment request checksCloned voices and video can impersonate leaders to request payments or access, so verification steps confirm those requests first.
  • AI tool rulesStaff sometimes paste company information into public AI tools, so FunctionOne sets rules for which AI tools staff can use with company information.

Frequently asked questions

Leaders often ask FunctionOne these questions before a security assessment.

What does a managed services provider do?

A managed services provider takes ongoing responsibility for running and monitoring a company's IT. FunctionOne provides both managed IT and cybersecurity services, covering daily support, monitoring, patching, backup, network management and security analysis for established mid-size and large organizations.

What's the difference between fully managed and co-managed IT?

Fully managed IT means FunctionOne runs all of a company's IT and security. Co-managed IT means FunctionOne works alongside an in-house IT team, filling gaps in monitoring, security or specialized support while the in-house team keeps day-to-day control.

What does 24/7 security monitoring cover?

FunctionOne's 24/7 security monitoring covers continuous watching of a company's connected systems, including Microsoft 365 accounts and email. Analysts investigate unusual activity and contain confirmed threats within response rules the client has approved in advance.

Does working with FunctionOne make a company compliant?

Working with FunctionOne does not make a company compliant on its own. FunctionOne's monthly reports and security records help leadership answer questions from auditors, insurers and regulators, but compliance depends on each organization's full set of policies and controls.

Where does FunctionOne work from?

FunctionOne works from an office in Syracuse, New York, and a second office in Tampa, Florida. The Syracuse office is located at 6216 Thompson Road, Syracuse, New York 13206, and the Tampa office is located at Industrious Downtown, 401 East Jackson Street, Tampa, FL 33602.

How does a company get started with FunctionOne?

A company can get started by booking a security assessment or calling 315-437-6714. FunctionOne reviews the company's systems and accounts, then agrees on scope and response rules with leadership before any monitoring or changes begin.
