A sweeping cyber intrusion into key U.S. institutions has turned cybersecurity stocks into a focal point, as investors reassess how exposed companies are to state-backed hackers and critical infrastructure risks. This shock to confidence can also be a source of opportunity, especially for stocks seen as part of the solution. This article introduces three cybersecurity stocks from our screener that appear positively exposed to this news and explains why each one matters now.

The stocks covered below are just a starting sample, since the full cybersecurity screen surfaced 33 more companies with equally compelling narratives that are not included here. To identify and analyze the rest of the field, head straight into the Cybersecurity Stocks screener

Cloudflare (NET)

Overview: Cloudflare is a cloud-based security and networking company that sits at the edge of the internet, providing DDoS protection, web application firewalls, Zero Trust access, secure web gateways and other tools that help keep websites, apps, corporate networks and critical infrastructure online and protected from cyberattacks. It also offers performance and developer services, but its core appeal in the current threat backdrop is its role as a security shield for enterprises, governments and key internet applications.

Operations: Cloudflare reports about US$2.5b in revenue from its Internet Telephone segment, with sales spread across the United States, Asia Pacific, Europe, the Middle East and Africa, and the rest of the world.

Market Cap: US$99.8b

Cloudflare provides direct exposure to cybersecurity at the internet edge, which is where state-backed attackers are probing critical institutions. Its Zero Trust, DDoS and secure networking tools are already used by governments and large enterprises, with management highlighting trust from federal agencies and multi year contracts that tie Cloudflare into sensitive workloads. Analysts are pricing in rapid growth and a return to profitability, so expectations are high and the stock trades on a premium that leaves little room for setbacks. Investors who want pure play cyber exposure need to weigh that valuation and margin pressure against Cloudflare’s role in protecting critical infrastructure and its push into AI driven security and agentic internet services, which the recent intrusion headlines bring into sharper focus.

Cloudflare’s premium price and AI push have many investors focused on the story at the surface. The real question is what the detailed DCF valuation analysis for Cloudflare reveals about how much optimism is already priced in and where expectations could break.

Koal Software (SHSE:603232)

Overview: Koal Software is a Shanghai based cybersecurity company that builds public key infrastructure platforms and identity security tools that help governments, financial institutions and enterprises encrypt data, authenticate users and secure critical communications.

Operations: Koal Software currently generates its reported revenue of about CN¥378 million entirely from China.

Market Cap: CN¥3.5 billion

Koal Software gives targeted exposure to identity and encryption infrastructure at a time when large scale intrusions are raising questions about how governments and enterprises secure access to sensitive systems. The company focuses on PKI, unified authentication and endpoint protection that are directly relevant to secure communication between ministries, banks and defense related customers. Analysts expect strong revenue and earnings growth over the coming years. However, the stock trades on a premium P/S multiple and is still loss making, which raises the bar for execution. In addition, the funding mix is tilted to higher risk borrowing and the company recently cancelled a private placement, which makes this a higher risk cybersecurity stock where contract wins and progress toward profitability will matter a lot.

Koal Software’s premium P/S and all China revenue create a story of high expectations that many investors only half see. Get the full context in the analyst forecasts for Koal Software, which also surfaces a critical funding twist.

Datadog (DDOG)

Overview: Datadog runs an observability and security platform that helps enterprises monitor their cloud infrastructure, applications and data in real time, while adding tools for application security, cloud security posture and threat detection that align closely with cybersecurity budgets.

Operations: Datadog reports about US$4.0b in revenue from Information Technology (IT) Infrastructure, with roughly US$2.7b from the United States and about US$1.2b from international markets including the rest of North America.

Market Cap: US$81.1b

Datadog gives you exposure to cybersecurity where many risks are now concentrated, inside complex cloud and AI workloads that governments and enterprises need to watch closely. The company combines observability with cloud security, SIEM and threat management, and is pushing further into government work after securing FedRAMP High certification in 2026. The stock trades on a premium valuation that reflects expectations for its security and AI focused strategy. At the same time, heavy investment, intense competition from hyperscalers and recent insider selling highlight that execution and customer retention may be as important as current headline growth metrics.

Datadog’s security and observability story is accelerating, yet many investors still treat it as just another monitoring tool. Read the analysis report for Datadog for the key risk reward twist that could change that.
