Understanding Who’s Responsible for What Under UK Data Protection Law

One of the most common questions we receive from clients relates to their data. “Why is Sarah’s mailbox full?” “What’s using all the space on our file server?” “Can you tell us what emails John has been deleting?”

These are perfectly reasonable questions, but the answers often surprise business owners. As your IT provider, we can tell you how much data exists and where it’s stored—but we can’t tell you what that data contains or make decisions about it. That’s not us being unhelpful; it’s data protection law working exactly as it should.

Understanding the difference between a data controller and a data processor is essential for every business owner. It clarifies responsibilities, prevents misunderstandings, and ensures your business remains compliant.

The Two Key Roles in Data Protection

UK data protection law defines two distinct roles when it comes to handling personal data. Most businesses will act as both at different times, but understanding which hat you’re wearing in each situation is crucial. Continue reading →

A Plain-English Guide for UK Business Owners

If you’ve ever felt confused by data protection terminology, you’re not alone. Many business owners we speak to aren’t sure whether they should be following “GDPR”, “UK GDPR”, or the “Data Protection Act”—or whether these are all different things entirely.

The good news is that once you understand the background, it all makes sense. This guide cuts through the jargon and explains exactly what UK businesses need to know about data protection law today.

A Brief History of Data Protection in the UK

Data protection law in the UK has evolved significantly over the past few decades. Understanding this history helps explain why we have the current framework. Continue reading →

Essential insights to help your business thrive in the digital age

As your trusted IT partner, we’ve compiled these essential facts to help you understand the technology landscape and make informed decisions for your business. Whether you’re looking to improve security, boost productivity, or plan for growth, these insights are relevant to businesses of all sizes and sectors across the UK.

 

1. Cyber attacks cost UK SMEs an average of £8,460 per incident

According to government research, small businesses are increasingly targeted by cybercriminals. Basic security measures like multi-factor authentication and regular software updates can prevent the majority of attacks—often at minimal cost.

2. 43% of cyber attacks specifically target small businesses

Smaller organisations are often seen as easier targets due to less sophisticated security infrastructure. A managed security service can provide enterprise-grade protection at SME-friendly prices. Continue reading →

As your trusted IT partner, we understand the unique challenges that small and medium-sized enterprises in the UK face. Microsoft has announced that Windows 10 will reach its end of support on 14th October 2025—a change that requires your attention now.

What This Means for Your SME

When Windows 10 support ends, your business will no longer receive:
– Critical security updates and patches
– Technical support from Microsoft
– Bug fixes for emerging issues
– Protection against new cyber threats

For SMEs already juggling multiple priorities with limited IT resources, this presents a significant risk to your operations and data security.

Why UK SMEs Should Prioritise Windows 11 Upgrade

Practical Security Benefits for Your Business
Windows 11’s enhanced security features are particularly valuable for UK SMEs, which are increasingly targeted by cybercriminals. Recent government statistics from 2022 show that 39% of UK small businesses reported cyber attacks that year, with an average cost of £4,200 per incident.

For small to medium-sized business owners in today’s digital landscape, protecting against cyber threats is critical to maintaining a reputable, secure operation. With email remaining one of the most common entry points for cyber-attacks, it’s vital that your Managed Service Provider (MSP) deploys effective security measures. At Trichromic LLP, we’re committed to safeguarding our clients by implementing email authentication protocols like SPF, DKIM, ARC, and DMARC. These tools help stop spam, phishing, and spoofing attempts that can put your business, employees, and customers at risk.

Understanding Email Authentication and Its Importance

The protocols SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), ARC (Authenticated Received Chain), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) work together to verify the identity of the sender and ensure that messages have not been altered during transmission. Here’s a quick rundown of what each protocol does:

1.  SPF: Checks whether the server sending an email is authorized by the domain’s owner, reducing the chance of fraudulent emails pretending to be from your domain.

2. DKIM: Adds a cryptographic signature to each email, ensuring that the message hasn’t been tampered with en route to the recipient.

3. DMARC: Provides your domain with a set of policies for handling unauthenticated emails. DMARC combines SPF and DKIM results and lets you specify how failed messages should be handled (quarantined or rejected) and receive reports on these failures.

4. ARC: Ensures the continuity of authentication for emails that are forwarded or relayed through third-party services. Without ARC, emails forwarded through services like mailing lists may fail authentication checks, leading to unnecessary rejections.

BT have recently confirmed that the switch-off of lines will now occur by January 31, 2027, rather than the original deadline of December 2025 – this includes the switch-off of Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN). This delay is a significant development for customers, and we feel it is important that you understand what it means for your business.
At Trichromic we want to keep our customers informed about the latest developments in the UK’s full-fibre future. For those who are currently using analogue (PSTN) or ISDN lines for calls, alarms, fax machines, PDQ machines or, CCTV, these will need to be replaced with digital solutions at some point.

Why the Delay?

The delay is primarily due to the need to ensure a smoother transition for vulnerable customers and those with additional needs. The extra time allows for a more comprehensive approach to migrating these customers to digital landlines, ensuring they receive the necessary support and equipment to maintain their connectivity.

Following on from our recent post regarding the switch-off of PSTN (the very old UK system phone system that runs on copper wires), we thought it would be a good idea to debunk some of the scare stories regarding digital phone lines that are doing the rounds.
The PSTN switch-off should be happening in 2025. From then on, at home or at work, we’ll all be using digital phone services. Many businesses have already successfully made the move to digital – they’re already enjoying the many benefits of a new phone system.

At Trichromic we understand that not everyone is fully conversant how digital phone systems work and you may have heard rumours that the technology is not as robust as it should be. We’d like to debunk some of these myths. Here goes:

1. Calls over the internet aren’t as good as those made over a normal phone line
They’re better. Back in the early days of internet calls this observation may have been true. But the tech is no longer new – there have been huge improvements in network connectivity. It’s sophisticated, and delivers crystal clear audio with no more dropouts, tinny voices, echoes, or delays. Continue reading →
