Independently verified by Assurix
Figures as of 2026-09-09. Verified figures are re-checked by Assurix every six hours, not once a year. Support figures are pulled from our internal support records — spam, duplicates and abandoned tickets excluded, and “same working day” means within our support hours excluding time waiting on the client. The live Assurix portal is temporarily offline while some reported errors are fixed.
What you actually get
The day-to-day service behind the number.
A helpdesk that answers
Critical issues are triaged in under 15 minutes, not logged and left. Every ticket goes to a person, not a queue you have to chase.
Devices managed and patched
Every laptop and server monitored and kept current, so vulnerabilities get closed before they get found — not discovered during an incident.
Microsoft 365, configured properly
Email, files and collaboration tools set up, secured and backed up — not left on whatever the default happened to be.
A security baseline that's always on
Endpoint protection, phishing filtering and a 24-hour Security Operations Centre watching your environment, not just your tickets.
Onboarding and offboarding, handled properly
New starters set up and leavers locked out without delay — no loose accounts sitting around as a risk.
On-site IT support is a separate agreement, not included as standard — we'll tell you upfront if your business needs it.

Switching
Moving to us doesn't have to be painful
The biggest fear when switching IT provider is landing somewhere no better, or being disrupted while you get there. We designed our process to remove both risks.
Full inventory first
Before anything moves, we document your entire environment — every device, account, system and integration. Nothing gets missed because nothing is assumed.
We work to your timeline
We fit around your business: avoiding busy periods, staging the transition, running parallel monitoring where the risk warrants it.
We handle the complexity
Licence transfers, security reconfiguration, documentation, team briefing — that is our job, not yours. Most clients are live with us within four to six weeks.
An objective measure from day one
Before you sign anything, you get your Technology Resilience Score™ — a benchmarked baseline, so you know you are switching to something demonstrably better.
The 90-Day Resilience Guarantee
We'll make your business more resilient in 90 days. If we don't, we stop charging.
And we don't ask you to take our word for it. We measure your resilience before we start, and again at day 90.
Most managed service providers guarantee how fast they answer the phone. We guarantee the thing that actually matters to your business: whether your technology gets more resilient.
Your Validated assessment sets your baseline. Before you commit to anything, you get your target score, your 90-Day Resilience Plan, everything we need from you, and every pound of investment we know is required to get there. No surprises at week three.
If we haven't hit the agreed target in 90 days, our management fee stops and we keep working. If after another 90 days we still haven't moved it, we'll tell you we're not the right provider and hand you over properly.
You don't have to claim it. No forms, no arguing, no submitting anything. If we miss the target, the fee stops automatically and we tell you.
Below 3.0 today
We'll lift you above 3.0 within 90 days. This is where the fastest, most valuable gains sit — and it's commonly where we see organisations starting.
Between 3.0 and 3.9
We'll improve your score by at least half a point within 90 days. In our assessments, we typically see organisations operating comfortably from 3.5 upward — that's the trajectory this puts you on.
4.0 or above
You're already operating at a strong level of resilience. The conversation shifts from protecting the business to using technology to grow it.
Your baseline comes from a Validated assessment, not an indicative score. Every action in your 90-Day Resilience Plan has a named owner and a date, agreed with you before we start. Where an action sits with you and isn't completed, the clock pauses rather than the guarantee ending — and you can see the status at any time. Third-party licences, hardware and project work outside the plan remain chargeable. Full terms form part of our Master Services Agreement. See our full 90-Day Guarantee terms.
How we measure it
The Technology Resilience Score™
Most organisations your size operate at 3.5 or above. Most we assess start below it. Your Technology Resilience Score™ measures your organisation's ability to prevent, withstand and recover from technology and cyber risks, on a scale of 1.0 to 5.0 — scored across ten domains. A score below 3.0 points to elevated operational risk and a clear stabilisation opportunity. Above 3.5, the conversation shifts from protecting the business to using technology to grow it.
On the call, you'll know your indicative score, where the gaps are, and what closing them would do for the business.
Why Little Big Tech
Little Big Tech is the first managed service provider to hold the Assurix trustmark. Our security posture is independently verified every six hours against outcomes derived from the NCSC's Cyber Assessment Framework v4.0 — the framework UK cyber regulators use to assess critical national infrastructure. Not once a year. Every six hours. We work exclusively with professional services businesses of 5 to 50 people across London and the South East.
We don't sell technology. We define the outcome, prescribe what delivers it, and take ownership of the result.
“My emails were hacked and LBT instantly stepped in — Matt and John were on the case before I even knew I had a problem. They sorted the issue and isolated my system immediately.”
Karen Woodbridge
“John was super quick to arrive onsite, and he assisted in fixing a software issue with our customer-facing devices. Without him, our busy day would have felt even busier.”
