About EFX Tech
We build the technology that businesses quietly depend on.
EFX Tech is a software engineering studio working with financial services firms, insurers and ambitious businesses. We design, build, integrate and support the systems behind their websites, their operations and their customer experience.
Why we exist
Good businesses deserve better than a patchwork.
We kept meeting the same situation: capable, well-run businesses held back by technology that had grown up by accident. A website from one agency, integrations from a freelancer who moved on, a critical spreadsheet only one person understands, and hours every week lost to re-typing data between systems.
Large enterprises solve this with in-house engineering teams. Most businesses can't justify one, and shouldn't have to. EFX Tech exists to give them the same quality of engineering, security and accountability, sized and priced for where they are today and able to grow with them.
Our name comes from the idea at the centre of everything we build: exchange. Information exchanged between systems without re-keying, value exchanged between businesses and customers without friction, and effort exchanged for automation, so people spend their time on work that needs a person.
How we think
Four beliefs behind every project.
They shape what we recommend, what we turn down, and how we measure whether we did a good job.
Technology is a means
We start from the result you need and work back to the software, never the other way round.
Reliability over novelty
Proven tools, clear designs and systems that behave the same way every day.
Automation serves staff
We automate the repetitive work and keep judgement with the people accountable for it.
No dependency on us
Documented, standard and owned by you, so you stay with us because you want to.
Security & data protection
Your clients' data is the most valuable thing we touch.
We handle it accordingly. Security is part of how we design, build and operate every system, not a phase at the end, and we are open with you about exactly how your data is protected.
- Least-privilege accessPeople and systems get only the access their job requires, reviewed regularly and removed promptly.
- Encryption everywhereData encrypted in transit and at rest, with secrets held in managed vaults, never in code.
- Secure developmentCode review on every change, automated dependency and vulnerability scanning, and security testing before launch.
- UK GDPR by designData minimisation, clear retention, documented processing and support for your data-protection impact assessments.
- Tested recoveryBackups verified by actually restoring them, and documented plans for when something goes wrong.
- ConfidentialityWe are happy to sign NDAs before discovery, and we treat everything you share as confidential by default.
