IonQ’s move to buy cybersecurity firm Elisity in an all stock deal worth up to US$1.3b has pulled quantum computing straight into the frontline of digital defense, and markets are paying attention. When a hardware player reaches for AI driven threat protection, it can reshape how investors think about risk, dilution and growth potential. This article breaks down three cybersecurity stocks exposed to this news, and why each one could be worth a closer look right now.
The stocks covered below are just a sample set, and the full screen surfaced another 54 cybersecurity focused companies with equally compelling stories that are not covered here. If you want to go straight to the source and identify your own highest conviction ideas, head into the Cybersecurity stocks screener.
Cellebrite DI (CLBT)
Cellebrite DI sits in the cybersecurity screener through its role in digital forensics and incident response, turning seized devices and cloud data into usable evidence for law enforcement and enterprises. The group generates about US$514 million from internet software and services and carries a roughly US$2.8b market value.
Cellebrite DI plugs into the cybersecurity theme at the investigation end of the chain, where agencies and corporates try to make sense of digital traces rather than just block threats at the perimeter.
“The accelerating shift by law enforcement and intelligence agencies toward more advanced digital investigation platforms, driven by surging digitalization, larger data volumes, and increasing crime sophistication, is fueling rapid adoption of Cellebrite’s cloud/SaaS solutions and digital forensics platforms (Inseyets, Guardian, Pathfinder).”
What happens to Cellebrite DI’s margins and pricing power depends heavily on how one unresolved pressure inside its public sector customer base plays out.
That unresolved pressure is exactly what the full narrative for Cellebrite DI unpacks, separating short term budget friction from longer term demand for Cellebrite DI’s digital investigation tools.
BlackBerry (TSX:BB)
BlackBerry now earns its place in a cybersecurity screen through secure communications, endpoint protection and embedded security, with its QNX software and related tools used by governments and enterprises that are spending directly on digital defense.
BlackBerry generates about US$300 million from QNX, US$274 million from Secure Communications and US$40 million from Licensing, against a market value near CA$7.5b.
For cybersecurity investors, BlackBerry matters because its security software sits inside critical infrastructure and vehicles rather than just on office laptops, tying its fortunes to long running digital risk budgets instead of short term IT refresh cycles.
“QNX charges automakers a royalty every time a car rolls off a production line. Once a design win is secured, that royalty flows for the entire model lifecycle: typically 5 to 8 years.”
What that stream ultimately means for BlackBerry’s earnings power hinges on how one quiet shift in safety critical software demand plays out.
That quiet shift is exactly what the full narrative for BlackBerry unpacks, highlighting where BlackBerry’s royalty engine could accelerate and where safety trends might still be masking risk.

Zscaler (ZS)
Zscaler is a pure-play cloud security provider built around zero trust, routing traffic through its platform rather than traditional hardware firewalls. The business generates about US$3.35b from subscription services to its cloud platform and related support, and carries a market value near US$38.1b.
Zscaler plugs directly into the cybersecurity screener theme as a cloud-based gatekeeper for zero trust and threat protection, and its pitch to large enterprises has been increasingly about consolidating tools and driving more value from each account rather than just adding new logos.
“Accelerating customer adoption of Zero Trust Everywhere and Data Security Everywhere solutions, particularly among Global 2000 and Fortune 500 firms, is fueling large upsell deals and higher ARR per customer, which should drive sustained double-digit revenue growth and improve net retention rates.”
What that upsell story ultimately means for Zscaler’s profitability and investor returns depends on how one pressure on its zero trust pricing power plays out.
That pressure point is exactly what the full narrative for Zscaler unpacks, mapping where Zscaler’s zero trust engine could keep accelerating and where pricing power risks might still be hiding.
