IT Provider Due Diligence · Fresh Mango Technologies
IT provider due diligence is the process of examining a prospective or incumbent IT supplier's capability, security, documentation, service levels and commercial terms before you depend on them — or before you renew.
Why due diligence matters
Your IT provider holds administrative access to your email, files, finances and client data. That is a level of trust normally reserved for auditors and bankers, yet it is frequently granted on the strength of a friendly meeting and a monthly price.
Good due diligence takes a few hours and prevents the two most expensive outcomes: appointing a provider who cannot deliver, and becoming dependent on one you cannot leave.
Capability and delivery
- Who will actually do the work, where are they based, and what cover exists during leave or illness?
- Which skills are in-house — networking, Microsoft 365, cyber security, servers — and which are subcontracted?
- What are the written response targets by incident priority, and how is performance measured?
- How are major incidents managed, communicated and reviewed afterwards?
- What on-island attendance is included, and what is chargeable?
Security and data protection
- How does the provider protect its own systems and the administrative accounts it uses to reach yours?
- Is multi-factor authentication enforced for every engineer, with individual named accounts rather than shared credentials?
- How is privileged access logged, reviewed and revoked when staff leave?
- How are your backups configured, and when was a restore last tested and evidenced?
- What is the provider's own incident response and breach notification commitment to you?
Ownership, documentation and exit
- Do you own your Microsoft 365 tenant, domain names, licence agreements and administrator accounts? The answer must be yes.
- Is your environment documented, and will you receive that documentation?
- What are the notice period and exit terms, and what handover is included at no extra cost?
- Are there tools or licences that would stop working if you left, and what is the plan for them?
Commercial terms
- Precisely what is included in the monthly fee, and what is chargeable?
- How are price increases handled and notified?
- Does the provider earn margin on hardware and software it recommends, and is that disclosed?
- Is there any minimum term, and what does it buy you?
How Fresh Mango helps
Fresh Mango Technologies will answer every question above about our own service in writing, and we will run the same review on your existing arrangement if you want an independent second opinion — including when the conclusion is that your current provider is doing a good job.
Frequently asked questions
What are the biggest warning signs in an IT provider?
Refusing to give you administrator access to your own Microsoft 365 tenant or domain; no written service levels; no documentation; backups never restore-tested; shared engineer accounts without multi-factor authentication; and reluctance to disclose hardware margins. Any one of these justifies a harder look.
Should our IT provider also handle cyber security?
They should deliver security fundamentals — patching, endpoint protection, identity hardening, backup — and many businesses also want independent assurance. Fresh Mango delivers specialist security through Complete Cyber Security, and we support clients who prefer a separate assessor for independence.
How often should we review our IT provider?
Formally at each renewal, and informally every quarter through service review data. A provider performing well will welcome the review; one that resists it has told you something useful.
Can we get an independent opinion on our current IT?
Yes. Fresh Mango offers an independent review of your environment, documentation, security posture and service arrangements, delivered as a written report you can use whatever you decide to do next.
