A practical starting point for Portsmouth

Start with your security responsibilities

For a business in Portsmouth, cyber security should follow the information and decisions it needs to protect. A contractor's company laptop is used on customer networks and accesses several shared project spaces. The review should explain which organisation controls each service and how project access is removed afterwards. This is an illustrative situation. Ask 39Support which controls, investigation coverage and response responsibilities your chosen plan includes. Set priorities around your own business.

Illustrative business scenario — use it to identify the questions that matter in your own organisation.

Define the security boundary

List the people, devices, cloud services and locations in scope, making third-party systems and business-owned responsibilities clear in the proposal. Document company-managed devices and customer-controlled networks separately, including the restrictions on assessment or changes to systems outside the business's authority.

Review external sharing

Identify who can approve guest access and shared links, then define how permissions are reviewed and removed when work ends. Review access to customer project material and the approved methods for exchanging it, identifying the owner who authorises continued access after work ends.

Remove access deliberately

Connect role changes and departures to account permissions, shared workspaces and equipment returns, preserving company records that authorised colleagues still need. Link the completion of a customer engagement to permission checks, local file decisions and equipment returns rather than relying on an employee's eventual departure.

How we support your business in Portsmouth

Our UK helpdesk provides a central route for your team. We agree the covered users, devices, locations and applications, then document onboarding and escalation responsibilities. The service is provided through an ongoing monthly agreement.

39Support’s operational office is in North Weald, Essex. Portsmouth is a service area, rather than a branch location. Physical attendance, travel arrangements and any site-specific response requirement are confirmed for your postcodes in the proposal.

Microsoft 365, devices and identity

Where appropriate, we combine Microsoft 365 Business Premium licensing with Intune management and Entra identity controls. Licence subscriptions, management and any Azure resource costs are itemised. Planned onsite cyber security and AI training can support your people as part of the agreed programme.

Before we speak

Your questions.
Clear answers.

Can Portsmouth contractors review security without assuming control of their customers' networks?

Use the free 60-minute IT review to discuss the priorities and working example described on this page. Bring the relevant systems, user roles and existing supplier arrangements to the conversation. The proposal should identify delivered controls, open improvements, investigation hours and incident responsibilities; any certification assessment or specialist project must be scoped explicitly.

Can we buy IT support and cyber security together?

Yes. We can scope a combined monthly service or managed cyber security that complements your existing IT team. The proposal accounts for controls already included and makes responsibilities clear.

Do your prices include Microsoft 365 licences?

Licences are itemised in the proposal. We confirm the subscription, billing commitment and any add-ons separately from management fees and Azure consumption.

Is the free review a full technical audit?

The free 60-minute review is a discovery and priorities discussion. Any detailed technical assessment requiring system access is separately scoped as part of onboarding or an agreed managed service.

Can you support our business and the devices we use?

Our focus is businesses with 5–200 staff. Standard IT support covers only devices that have completed onboarding into the agreed Microsoft management environment and are on the approved inventory. Covered hardware must be under three years old, supported computers must run Windows 11 Pro, users must use Microsoft 365 Business Premium, and the environment must meet the Cyber Essentials technical standard. We identify gaps before agreeing live support.

How do you take over from our current IT provider?

We review your current agreement, user and device inventory, Microsoft 365 tenant, domains, licences, backups and administrator access. We then agree the handover actions, owners and timing. Your people receive the new support route when the managed service goes live.

Will we have to change our email addresses or lose Microsoft 365 data?

A provider change does not automatically require new email addresses or a new Microsoft 365 tenant. We review ownership, access, licence commitments and the existing setup first. Any migration or configuration change is planned and scoped before it takes place.

Will the handover disrupt our business?

We identify dependencies and plan changes around your operations. If a change needs an interruption, we discuss the window and the affected systems in advance. We do not promise a disruption-free outcome before reviewing the environment.

What if our current provider cannot supply all the access or information?

We list the missing items and agree a route to obtain them through the authorised owner, existing supplier or relevant platform. We do not bypass ownership or access controls. Missing access and its effect on the handover are made clear before live support is agreed.

Do you support our specialist or third-party applications?

Third-party and line-of-business application support is excluded from the managed IT plan. Your software supplier handles application-specific faults. We identify the boundaries during discovery and document the Microsoft devices and services we will manage.

What if we are unhappy after switching?

Eligible managed IT support has a 90-day double your money back guarantee. It covers twice the qualifying IT support management fees paid during the first 90 days, subject to the published onboarding, device and licensing requirements. Hardware, licences, cyber security, projects, training and third-party application support are excluded.
