A national outage at Telstra has put network resilience and time-keeping systems under the spotlight, and that attention can quickly flow to cybersecurity and infrastructure stocks linked to these issues. When critical services go offline for hours, decision makers often reassess how they manage risk, redundancy, and incident response. For investors, that raises practical questions about which companies might benefit as organisations review their defences, and which ones could face tougher scrutiny. This article looks at three stocks from a Cybersecurity and Network Resilience Providers screener that appear positively exposed to the fallout from the Telstra outage.

Climb Global Solutions (CLMB)

Overview: Climb Global Solutions is an IT distributor and solutions provider that connects software and hardware vendors with resellers and end customers across the United States, Canada, the United Kingdom, and Europe, with a strong focus on cloud, security, networking, and infrastructure tools. Through its Climb Channel Solutions and Grey Matter businesses, it helps organisations source, manage, and support complex technology stacks.

Operations: Climb Global Solutions generates most of its revenue from Distribution at about US$672.4m, with Solutions contributing around US$24.5m, and the United States accounting for the bulk of sales at about US$544.9m, followed by the United Kingdom, Canada, and Europe.

Market Cap: US$453.7m

Climb Global Solutions sits squarely in the spotlight after the Telstra outage because its portfolio includes software for data backup, disaster recovery, and information management that directly targets the kind of uptime and resilience gaps many enterprises are now rethinking. Some analysts see sizeable upside, and the stock trades below certain estimates of fair value. However, profit margins around 3% and reliance on higher risk external borrowing contribute to a meaningful risk profile. Recent moves, such as expanding the board with deep cybersecurity experience and adding vendors like Ivanti, indicate that Climb Global Solutions is working to deepen its role in mission critical infrastructure. At the same time, concentration in key vendors and low margins mean investors may wish to consider both the potential opportunities and the operational pressure points.

Climb Global Solutions is sitting at the intersection of resilience spending and thin margins, and investors are not yet seeing the full picture. Get the Climb Global Solutions financial health report to see what its balance sheet might be hiding.

Tracsis (AIM:TRCS)

Overview: Tracsis (AIM:TRCS) provides software, hardware, data analytics, and related services that help rail and wider transport operators plan timetables and resources, manage incidents, monitor assets in real time, and control large scale events more efficiently and safely across the UK and internationally.

Operations: Tracsis generates about £39.2m from Rail Technology & Services and £45.3m from Data, Analytics, Consultancy & Events.

Market Cap: £96.8m

Tracsis is aligned with the renewed focus on network resilience after the Telstra outage, as its rail and transport software addresses the kind of planning, incident management, and real-time monitoring gaps that can cause widespread disruption. The company trades on a relatively rich P/E and relies on higher-risk external borrowing, which introduces financing and valuation risk. Earnings have recently been supported by a pipeline that includes acquisitions such as RailComm and Vesputi, alongside growing international exposure. This may position the business to participate if operators increase investment in reliability, although investors still need to weigh modest revenue growth and low current margins against those potential rewards.

Tracsis appears to be a reliability story priced for perfection, featuring a rich P/E and growing international exposure that many investors might be overlooking. Before letting that optimism run ahead of reality, read the analysis report for Tracsis

Codan (ASX:CDA)

Overview: Codan (ASX:CDA) supplies secure communications systems and metal detection equipment to defence, government, security agencies, corporates, and small scale miners around the world. Its products are used in demanding environments where reliability and uptime are critical.

Operations: Codan generates about A$448.3m from Communications and A$307.8m from Metal Detection, with a small A$6.1m contribution from Other activities. It sells into markets including the United Arab Emirates, the United States, and other international regions.

Market Cap: A$8.1b

Codan stands out in a post Telstra outage world because its secure communications hardware and DTC and Zetron platforms sit close to the heart of mission critical networks, from defence and public safety through to complex industrial operations. Earnings and revenue have both been growing at double digit rates, supported by high quality earnings, strong ROE of 23.1%, and net profit margins around 16.9%. However, the stock trades on a rich P/E and relies on higher risk external borrowing, which raises questions about how much optimism is already priced in. Heavy exposure to the cyclical gold detection business and competitive pressure in communications round out a story where investors could be missing some important details on both resilience and risk.

Codan’s high quality earnings, 23.1% ROE, and 16.9% margins suggest a stronger engine than many investors credit, but the real story may sit in the analyst forecasts for Codan and how its gold exposure could twist that path.
