3 UK Software Stocks Banks Could Turn To After The Google Cloud Outage

Simply Wall St·10/20/2026 23:34:25
Listen to the news

Cloud resilience moved from back-office concern to front-page story after UK regulators pulled Google and other major providers into the spotlight over a severe outage. That scrutiny may push banks to rethink how they monitor and test their digital plumbing. For investors, that could shift attention toward UK-listed software specialists tied to observability and incident response. This article examines three such stocks connected to that news story.

The three stocks discussed below are a focused sample. The full screen surfaced 12 more UK software companies with equally strong cloud resilience and observability narratives that are not covered here. If you want to go straight to the source and identify which vendors best match your own thesis on bank-grade reliability, analyze the Cloud Resilience and Observability Software for Financial Institutions screener.

Shearwater Group (AIM:SWG)

Overview: Shearwater Group provides cyber security software and managed security services focused on monitoring, incident response and resilience for large organisations.

Operations: Shearwater generates about £33.1 million from Services and £1.8 million from Software, with roughly £30 million earned in the United Kingdom.

Market Cap: £17 million

Shearwater Group sits in the crosshairs of the screener theme, offering cyber monitoring, incident response and resilience services that speak directly to banks concerned about cloud concentration risk and operational outages.

"Rising cybercrime, wider use of AI by attackers and tighter data regulation are prompting corporates and government departments to allocate more budget to cybersecurity. Inclusion in G Cloud 14 and the expanded submission to G Cloud 15 with more than 50 solutions increases exposure to U.K. government spending on cybersecurity."

An important consideration is what happens to Shearwater Group’s margins and contract visibility if one unseen pressure on how those budgets are deployed shifts meaningfully.

If that pressure point is on your radar, read the full narrative for Shearwater Group to see how budget timing, contract mix and execution risk could be decoupling.

Kainos Group (LSE:KNOS)

Overview: Kainos Group delivers digital transformation projects and Workday based software and services that help regulated clients manage data, resilience and compliance.

Operations: Kainos Group generates about £241.7 million from Digital Services, £107.6 million from Workday Services and £81.7 million from Workday Products across the U.K. and internationally.

Market Cap: £1.5b

Kainos Group matters for this cloud resilience screen because it sits where regulated clients upgrade critical HR and finance systems to monitored, auditable cloud platforms.

"Deepening product collaboration with Workday, including exclusive resale of Pay Transparency and participation in the Clear Skies initiative, is described as expanding addressable markets and supporting sustained double digit ARR growth. This is in turn expected to drive higher software led revenue and operating leverage."

The real test for Kainos Group is how one quiet shift in large client spending patterns ultimately filters through to margins and cash generation.

That spending shift is the crux of the story, and the full narrative for Kainos Group unpacks whether changing client priorities are accelerating or quietly stalling Kainos Group’s momentum.

SysGroup (AIM:SYS)

Overview: SysGroup provides managed IT and cybersecurity services with AI driven monitoring, 24/7 support and resilient data protection for UK clients.

Operations: SysGroup generates about £18.4 million from Managed IT Services and £3.7 million from Value Added Resale, mostly in the United Kingdom.

Market Cap: £30.6 million

SysGroup fits directly into the cloud resilience theme, combining AI based monitoring, cyber incident response and backup services that address the needs of banks concerned about outages at large cloud vendors. The firm has won new multi year cyber resilience contracts in regulated style sectors. Future demand from financial institutions could depend on how one unresolved profitability question affects its capacity to keep investing in these capabilities.

That profitability question is exactly what the SysGroup financial health report helps you unpack so you can judge whether SysGroup’s resilience ambitions and balance sheet strength really align.
