The best explanation of CTS begins with a lawyer watching a frozen screen. For a conventional office worker, a slow application is irritating. For a solicitor, it can consume a billable six-minute unit, stall a property completion or leave a client waiting while a deadline keeps moving. CTS built a company around understanding that difference. From Daresbury, Cheshire, it supplied cloud infrastructure, managed support, cybersecurity, disaster recovery and technology advice to law firms and barristers' chambers in Britain and Ireland. Its product was not merely computing. It was computing translated into the peculiar economics and anxieties of legal work.
That narrowness was the point. A general managed service provider might know Microsoft Azure or VMware. CTS claimed fluency in the systems sitting on top: iManage, LexisNexis Visualfiles, BigHand, Aderant, NetDocuments and the other software through which matters, documents, time and money flow. It could talk to an IT director about a hybrid-cloud roadmap and to a managing partner about fee-earner productivity. Customers included AFG Law, Thorntons, Turcan Connell, Seddons, Town Legal, Langleys and Taylor Rose MW.
A company built around one adjective: legal
Nigel Wright founded Converge-IT.Net in 2006. The name later contracted into CTS, and the positioning sharpened into “IT Services Shaped for Law.” The pitch was almost Ogilvian in its clarity: do not buy generic IT and spend your days explaining legal practice to it. Buy the team that already understands confidentiality, regulatory scrutiny, partner politics, specialist applications and the cost of a lost working minute.
The business made money in the familiar MSP fashion - recurring contracts for hosting, support, monitoring, backup and security, with consultancy and migration projects layered on top. The contracts exchanged lumpy in-house infrastructure spending for an ongoing service relationship. A law firm gained access to expertise it might struggle to recruit alone. CTS gained predictable revenue and a close view of the customer's future technology decisions.
The CTS commercial loop
In practice, the work could be pleasingly unglamorous. For Langleys Solicitors, CTS reviewed the infrastructure beneath a move to LexisNexis Visualfiles, then recommended a network upgrade, hardware refresh and VMware. Rather than discard everything, it produced a three-year roadmap that reused existing investment while preparing for what came next. Managed disaster recovery, email security, archiving and 24-hour support surrounded the core system. This was the method at its best: start with how the law firm works, then build the plumbing around it.
“The market wants different stuff from us.”Nigel Wright, describing CTS's strategic turn in 2023
What changed their mind
Private-equity firm Tenzing backed a management buyout in 2018. The amount was not disclosed, but the direction was visible. In 2020 CTS acquired City Business Solutions, a specialist in barristers' chambers, and Sprout IT, which brought a London base and 24-hour support operations in New Zealand. The three businesses adopted one CTS brand in 2021. In 2022 CTS bought Tiger Eye, a prominent iManage partner. Again, the price stayed private.
The acquisitions were not random roll-up arithmetic. They filled a strategic diagram. CBS added chambers. Sprout added scale and a follow-the-sun service desk. Tiger Eye added the document-management layer used by much of the upper legal market. By July 2023, Wright said CTS was heading toward £30 million in turnover and that the old private-and-public-cloud formula, while successful, no longer matched what clients wanted.
Law firms were trying to simplify increasingly tangled estates. Platform vendors did not always understand applications; application vendors did not always understand platforms. CTS wanted to occupy the join. Its new ambition was to move from a mid-market British MSP to a global digital-transformation partner that could rationalise both. A firm would have fewer suppliers to coordinate and one party answerable for performance. This was a rational response to customer demand. It also placed more eggs, cables and passwords in one basket.
The outage arrives at conveyancing speed
In November 2023, CTS disclosed a cyber incident and service outage. Access to data was severely limited for some customers. Public reports identified law firms whose operations were affected and described property transactions caught in the delay. One homebuyer told TechCrunch that an exchange had slipped while a mortgage offer approached expiry. CTS notified the Information Commissioner's Office and brought in third-party experts.
What failed first? Publicly, it was availability. Customers reported losing access to case files and core systems. The exact intrusion path was never confirmed by CTS. Security researchers discussed a possible connection to the CitrixBleed vulnerability, but that remained an outside assessment, not a company finding.
CTS organised restoration into four phases. The final phase - restoring client environments - was described as complex and without a precise completion time. PwC later said operations were fully restored by the end of December.
Restoring service did not restore the balance sheet. PwC said the disruption created financial pressure and prompted a sale process. On 4 April 2024, Converge-IT.Net, City Business Solutions UK and Sprout Technologies entered administration. Bluecube Cyber Security Solutions, part of Ekco, bought substantially all of the business and assets. All 140 employees across those MSP entities transferred. The consideration was undisclosed.
Tiger Eye was not included. It had maintained its own profit-and-loss account, separated from CTS and continued independently with Tenzing's backing. The administrators completed distributions, asset realisations and the closing of accounts in October 2025. Companies House recorded Converge-IT.Net Limited as dissolved following liquidation in January 2026. The CTS name may survive in old social pages and acquired infrastructure, but the Daresbury company profiled here does not survive as the independent operator it was.
The same model, read from both ends
The useful bits are still useful
It would be easy, and lazy, to let the incident swallow the preceding 17 years. CTS found a genuine market gap. Vertical expertise made a technical service legible. Its people knew why a document-management migration could not be separated from infrastructure, why a partner's tolerance for downtime differed from an ordinary department's and why a hybrid design might suit a firm that wanted Azure's flexibility without moving every sensitive workload at once.
Customers can copy the buying discipline, too. Thorntons did not choose a generic cloud label. It chose a design that could shift resources between private and public environments in line with its roadmap. Town Legal moved from a shared desktop to laptops because mobility and growth demanded it. Langleys connected infrastructure work to a specific case-management change. In each example, the technology followed an operating requirement instead of leading a parade of fashionable nouns.
Five things worth stealing
- Choose a customer narrow enough that its vocabulary becomes your product.
- Map technical performance to the customer's unit of value - for lawyers, productive fee-earner time.
- Reuse sound infrastructure and phase change through a visible multi-year roadmap.
- Join platform and application expertise, but keep ownership and escalation lines explicit.
- Test continuity without the provider: separate credentials, communications, backups and recovery evidence.
The last point is the one CTS's history adds in red ink. A disaster-recovery promise cannot stop at a failed server or damaged office. Customers need a plan for the provider itself becoming unreachable, compromised or insolvent. That means independently tested backups, current asset and data maps, emergency contacts outside the normal help desk, clear export rights and rehearsed manual workarounds for the handful of matters that truly cannot wait.
Procurement teams should ask for evidence, not adjectives: the date of the last restore test, the people allowed to trigger it, the systems excluded from it and the time required to rebuild identity services before anybody can open a document. They should also know whether the emergency status page, telephone tree and credential vault depend on the same environment they are meant to rescue. A glossy continuity plan stored inside the affected network is an unusually expensive piece of stationery.
This model also has limits. Deeply specialised managed service is expensive compared with self-service public cloud, and it works poorly for a tiny firm with simple software and strong internal skills. A single-partner approach is a bad bargain when contracts obscure subcontractors, recovery responsibilities or exit mechanics. It is especially unsuitable when a customer cannot verify isolation between tenants, recovery-time claims or who controls privileged access. Convenience is valuable. Unexamined dependence is merely convenient until Tuesday morning.
Bluecube's purchase preserved jobs and continuity, a better ending than abrupt shutdown for staff and customers. Yet the strongest conclusion belongs earlier in the story. CTS won because it could see a law firm from the inside. It faltered after an event that made customers see their infrastructure from the outside - as a chain of dependencies with one unusually important name in the middle. Both observations are worth keeping.
