IT providers for property and real estate

There are 99 IT providers serving Property & Real Estate clients listed in the Assurix directory.

Last updated: 17 August 2026

Property runs on trust and on timing. A sale completes, a deposit moves, a tenancy starts, and money changes hands at each step. That makes the sector a known target for people trying to redirect a payment or slip into an email thread at the wrong moment.

The businesses here also hold a lot of sensitive material. Estate and letting agents handle client money and keep identity documents gathered for anti money laundering checks. They hold personal data for tenants, landlords and buyers. And the work rarely stays in one office, with staff moving between branches, viewings and cars.

This page lists IT providers that work with property and real estate firms. Providers carrying the Assurix Trusted MSP badge are shown first, and any working toward it appear as On the Journey. Each provider's listing shows its current Assurix status. Below is what a good provider should be able to evidence, and how to check any provider's status for yourself.

What a good property IT provider should be able to evidence

Property mixes large payments, sensitive documents and staff on the move. Here's what a capable provider should be able to show you.

Guarding against payment redirection
Property deals move large sums between parties, which makes payment redirection and email interception a recognised risk. A provider should be able to explain how they help protect your email and reduce the chance of a fraudulent payment instruction getting through.
Protecting client money and ID documents
Agents handle client money and hold identity documents collected for anti money laundering checks. A capable provider can show how they help keep that money data and those documents secure, with access to them limited.
Looking after tenant, landlord and buyer data
Agents hold personal data for tenants, landlords and buyers under UK GDPR. Ask a provider how the systems they run help you store that data safely and control who can see it.
Securing mobile and branch-based staff
Branch networks and mobile agents mean people work from properties and cars, not only a desk. A good provider can describe how they keep laptops and phones secure when staff are out and about.
Keeping management systems dependable
Property management firms rely on systems for maintenance, compliance records and rent collection. A provider should be able to show how they keep those systems available and the records inside them protected.

Questions worth asking a property IT provider

Put these to any provider you're considering. The answers show whether they understand how money, data and mobile staff come together in property.

  1. How do you help protect us against payment redirection and email interception? Large sums move during transactions, and this is a recognised way fraud gets in.
  2. How do you keep client money data and the identity documents we hold safe? This material is sensitive and tightly regulated, so access needs controlling.
  3. How do the systems you run help us look after tenant, landlord and buyer data? Personal data carries obligations under UK GDPR.
  4. How do you secure laptops and phones used by staff working from branches, viewings and cars? Devices out of the office face different risks to those at a desk.
  5. How do you keep our property management systems available and their records protected? Maintenance, compliance and rent collection all depend on them.
  6. Can you show independent evidence of your security rather than just describe it? Continuous, independent proof gives you more to go on than a verbal reassurance.

The security reality for property and real estate

Property is a sector where money and identity meet. A single transaction can involve large payments passing between buyer, seller, agent and solicitor, and that flow of money has made payment redirection and email interception a recognised risk. A convincing fake instruction sent at the right moment can do real harm.

Agents sit at the centre of this. They handle client money and hold identity documents collected for anti money laundering checks, alongside personal data for tenants, landlords and buyers under UK GDPR. That's a lot of sensitive material to keep safe and to control access to.

The way the work happens adds to the challenge. Branch networks and mobile agents mean staff operate from properties, viewings and cars, not only a central office, so devices travel and connect from all sorts of places. And property management firms lean on their systems for maintenance, compliance records and rent collection, so those systems staying dependable matters day to day. A provider who knows the sector builds around all of this.

What the Trusted MSP badge means, and how to check it

Assurix is an independent trustmark for UK IT providers, built on proof, not promises. When a provider holds the Trusted MSP badge, it has passed all 64 controls in the framework, aligned to the NCSC Cyber Assessment Framework, and is checked through continuous monitoring rather than a yearly audit. You can see the current status on any provider's own listing, so it's worth checking directly as you compare your options.

Frequently asked questions

What is payment redirection fraud and how does it hit property deals?

Payment redirection fraud is when someone tricks a party into sending money to the wrong account, often by getting into an email thread and changing the bank details on an instruction. Property is a target because deals involve large payments moving between buyer, seller, agent and solicitor, so a single redirected transfer can be very costly. A good IT provider helps by protecting your email, making it harder for outsiders to pose as you, and helping staff spot a suspicious change. Ask what they put in place for this.

We hold ID documents for AML checks. What should our provider be doing?

Those documents are sensitive, and holding them for anti money laundering checks means keeping them secure and limiting who can open them. A capable provider helps by controlling access to the systems where the documents live, keeping those systems patched, and making sure the data isn't sitting somewhere exposed. They should also help you know who has looked at what. Ask how they protect this material specifically, since it's exactly the kind of data that causes serious problems if it leaks. Client money data deserves the same care.

A lot of our staff work out of the office. Does that raise the risk?

It changes it. Branch networks and mobile agents mean laptops and phones are used from properties, viewings and cars, connecting through all sorts of networks rather than one office setup. That widens the ways a device could be lost or a connection misused. A good provider plans for it, keeping devices encrypted, up to date and able to be locked or wiped if one goes missing. Ask how they secure staff who are rarely at a desk, because that's how much of property work actually happens.

If a provider here doesn't hold the Assurix badge, does that mean they're not secure?

No. The Assurix Trusted MSP badge is a relatively new, independent check, and a provider not holding it says nothing bad about their security. Many strong providers simply haven't been through it. The badge gives you an extra, independent signal when a provider does hold it, showing they've passed all 64 controls. Alongside it, lean on the questions above, on sector experience and on references. And check each provider's listing directly, since statuses can change over time.

What does UK GDPR mean for the data we hold as an agent?

As an agent you hold personal data for tenants, landlords and buyers, and UK GDPR sets out how that data should be looked after. In practice it means storing it safely, controlling who can reach it, and being able to account for how it's handled. Your IT provider plays a part in this by keeping the systems the data sits in secure and access properly managed. They can't take on your legal duties for you, but they can make meeting them a lot easier. Ask how the systems they run support your obligations.
