Independent support for Microsoft systems that are out of support or about to be.
Penta Consulting keeps older Microsoft infrastructure and business applications secure, compliant and running while you plan your next move. We cover Exchange, SharePoint, SQL Server, Windows Server, Project Server and Dynamics, with on-site or remote coverage and 24/7 technical support across multiple time zones.
Your Microsoft systems keep running. Their security updates do not.
Systems past end of support do not stop working. They stop receiving security patches, so each new vulnerability stays open. It is believed that 42% of SMEs still run unsupported Microsoft infrastructure
This is a business risk as well as an IT issue:
- Security risk. Unsupported systems carry unpatched vulnerabilities.
- Compliance risk. Running unsupported software can put you at odds with GDPR, FCA and NIS2 obligations.
- Financial risk. Breaches and downtime cost money and disrupt operations.
What we do for legacy Microsoft environments
- Protect unsupported systems now. We put compensating controls and monitoring around systems that no longer get vendor patches.
- Stay compliant. We map your estate to the regulatory frameworks you answer to and document how risk is being managed.
- Migrate without risking operations. We run the move to supported platforms in stages so live services stay up.
- Buy time for the right decision. Extended support keeps legacy systems running while newer platforms are introduced.
Your Microsoft infrastructure is
already at risk.
It's believed 42% of SMEs are still running unsupported Microsoft Infrastructure.
Unsupported systems don’t fail immediately, but they do become exposed.
Secure, manage and continue to operate with Penta Consulting before your systems become vulnerable.
Do you know the status of your systems?
Most SME organisations are still running critical Microsoft systems that no longer receive security updates, or are about to lose support entirely. This may not seem urgent, because these systems don’t simply stop working. But they do become immediately vulnerable.

How to choose a Microsoft legacy support provider
If you are comparing providers for a long-term maintenance contract, ask each one:
- Which products and versions do you support? Look for named coverage, such as Exchange, SharePoint, SQL Server and Windows Server, not a generic promise.
- What are the response times and coverage hours? Check for 24/7 support and the time zones covered.
- Is support on-site, remote or both?
- How do you handle compliance? Ask how they document controls for GDPR, FCA and NIS2.
- What is the exit plan? A good provider plans the migration to a supported platform alongside the support contract.
- Who does the work? Ask about the depth of the consulting team behind the service.
