3 Cybersecurity Stocks Worth Buying as AI Transforms Cyber Defense

An updated edition of the Feb. 12, 2026, article.

Cybersecurity has shifted from being just an IT task to a major business priority. With companies facing constant cyberattacks, from ransomware to phishing schemes to major data breaches, the stakes are high. Cyberattacks don’t just disrupt operations. They can lead to major financial losses and lasting brand damage.

That’s why cybersecurity has become one of the fastest-growing global industries. Fortune Business Insights expects the global cybersecurity market to jump from $218.98 billion in 2025 to nearly $699.39 billion by 2034 at a 13.8% compound annual growth rate. This surge reflects not only stronger demand but also the growing complexity of digital networks, new compliance requirements and the urgent need to protect critical data. Leaders like Palo Alto Networks PANW, CrowdStrike Holdings CRWD and Fortinet FTNT are already monetizing this demand with platforms built for modern threats.

Today’s attacks are smarter and faster than ever, and traditional security tools are falling behind. This is where artificial intelligence (AI) comes in. AI can analyze vast volumes of data and detect potential threats before they escalate. It shifts cybersecurity from reactive to proactive. The pace at which threats emerge means companies need to automate their detection and response processes, and AI is the most promising way to do that.

Companies like F5, Inc. FFIV, Cisco Systems CSCO and A10 Networks ATEN are leaning heavily into AI. They're upgrading their platforms to detect and respond to threats more quickly and intelligently. This not only makes their products more valuable to customers but also gives them a stronger position in a fast-growing industry.

3 Cybersecurity Stocks to Buy

F5 specializes in application security, multi-cloud management and networking solutions. Formerly known as F5 Networks, the company helps enterprises secure and deliver applications across on-premises and cloud environments, with an increasingly focused emphasis on AI-driven security and software-as-a-service solutions.

F5 is transforming from a traditional hardware provider into a critical AI-native security and infrastructure company, driving growth through its Application Delivery and Security Platform and Distributed Cloud Services. The company is experiencing strong momentum, with AI-related revenue and customer acquisitions rising significantly.

In January 2026, the company launched F5 AI Guardrails and F5 AI Red Team, which help enterprises protect their AI models and application programming interfaces (APIs) from data leakage and adversarial attacks. Its collaboration with NVIDIA integrates F5 technology into graphics processing unit (GPU) inference environments, allowing customers to maximize token efficiency, turning automated AI traffic into identifiable, billable transactions. By embedding AI assistants and automation into its Distributed Cloud platform, F5 is driving software-centric, recurring revenue growth, positioning itself as a vital infrastructure layer for secure, hybrid AI deployments.

While direct AI revenues remain early, demand is building as enterprises modernize their IT stacks. With AI driving higher application complexity and security needs, this Zacks Rank #2 (Buy) company’s platform approach should support steady software growth and long-term expansion. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

Cisco Systems offers cybersecurity products and services that prevent unauthorized access to system resources and protect from worms, spam, viruses and other malware. The company has been integrating AI into its product portfolios across networking, security, collaboration and observability.

Strong demand for Cisco’s products in developing AI infrastructure has been a game-changer for the company. In the second quarter of fiscal 2026, the company received $2.1 billion worth of AI infrastructure orders from web-scale customers.

Data center switching orders continue to register solid year-over-year growth in the fiscal second quarter, implying strong demand. These orders are coming from some of the biggest players in cloud computing and reflect a growing demand for AI-optimized networks. Cisco Systems is expanding its AI portfolio for data centers with new solutions like the Unified Nexus Dashboard, Cisco Intelligent Packet Flow, configurable AI PODs and 400G bidirectional (BiDi) optics.

As cyber threats become more sophisticated, Cisco Systems’ AI-powered platform gives it a competitive edge. These innovations are likely to accelerate customer adoption and support strong long-term revenue growth for this Zacks Rank #2 company.

A10 Networks provides software-based application networking solutions. A10 Networks is embedding AI across its security and infrastructure stack, and these initiatives are increasingly shaping its growth outlook. Its Advanced Core Operating System now includes an integrated AI stack that can interface directly with customer AI inference and generative AI systems, helping optimize performance and reduce infrastructure complexity. This allows A10 Networks solutions to offload compute-heavy tasks from GPUs and central processing units, improving throughput and latency for AI workloads, an advantage as enterprises scale AI deployments.

The company is also building AI-native security tools. Its AI firewall protects large language models by inspecting prompt-level traffic to detect threats like data leakage and prompt injection. Its DDoS (Distributed Denial of Service) solutions use machine learning and automated mitigation to detect anomalous behavior and block attacks in real time.

These capabilities are already gaining traction. Microsoft selected A10 to help secure mission-critical generative AI workloads, highlighting demand for its technology in hyperscale environments. By securing AI infrastructure and improving performance for AI workloads, A10 Networks is positioning itself as a critical enabler of enterprise AI adoption. ATEN currently carries a Zacks Rank #2.
