Cybersecurity has shifted from a line item into a strategic priority as enterprises race to secure AI workloads, contain identity sprawl, and protect data pipelines that now carry mission-critical traffic. Yet several quality names in the sector still trade in single- and low-double-digit territory, giving retail investors a rare chance to buy growth at compressed valuations. With AI-driven threats accelerating and digital transformation budgets holding firm, the under-$30 corner of cybersecurity looks like genuine opportunity.
With that in mind, here are three cybersecurity stocks trading under $30 that look worth a closer look right now.
SentinelOne (NYSE: S)
SentinelOne (NYSE:S | S Price Prediction) runs the AI-native Singularity platform, expanding from endpoint protection into data, cloud, and AI-driven SIEM. Shares recently traded near $15.60, a price that puts a roughly $5.07 billion market cap on a company that just crossed the $1.06 billion ARR mark.
Q3 FY26 revenue rose 22.9% year over year to $258.91 million, while non-GAAP EPS of $0.07 blew past the -$0.17 consensus. The non-GAAP operating margin hit a record 7%, expanding roughly 1,200 basis points year over year. Wall Street’s average target sits at $18.56, with 23 Buy or Strong Buy ratings versus 14 Holds.
The bull case is straightforward: profitability is inflecting, AI-native demand is real, and roughly 50% of bookings now come from emerging Data, AI, and Cloud products. CEO Tomer Weingarten said the platform “combines data, intelligence, and defense.” The risk: SentinelOne remains GAAP unprofitable, and a potential $136 million tax settlement with the Israel Tax Authority looms. For investors comfortable with a turnaround story, S looks compelling.
Tenable Holdings (NASDAQ: TENB)
Tenable Holdings (NASDAQ:TENB) is the exposure management leader behind Tenable One and the newly launched Hexa AI agentic engine. The stock recently changed hands near $20.83, well below the $27.10 analyst target and a 52-week high of $35.69.
Q1 FY26 revenue grew 9.6% to $262.06 million, with non-GAAP EPS of $0.47 beating estimates by 13.14%. Non-GAAP operating margin expanded 320 basis points to 23.6%, recurring revenue held at 96%, and management raised full-year guidance to $1.068 billion to $1.078 billion in revenue. The company also bought back 6.1 million shares for $130 million, with $338 million still authorized.
CEO Steve Vintz said exposure management is “essential in an AI-accelerated threat landscape.” A forward P/E around 11x on a profitable, recurring-revenue model with aggressive buybacks looks dislocated. The risk: cash declined from $187.8 million to $139.2 million due to the buybacks, and revenue growth is moderating. Even so, TENB looks like quality on sale.
A10 Networks (NYSE: ATEN)
A10 Networks (NYSE:ATEN) provides application networking and security infrastructure, increasingly tied to AI data center buildouts. Shares trade near $27.04, up 53.3% year to date and 67.1% over the past year, yet still under our $30 ceiling.
Q1 FY26 revenue jumped 13.4% to $75.0 million, with enterprise revenue surging to $42.20 million from $27.10 million a year earlier. Non-GAAP EPS of $0.24 beat estimates, and net income climbed 26.08%. Management reiterated full-year guidance for 10-12% revenue growth and 28-30% adjusted EBITDA margins, and continues to pay a $0.06 quarterly dividend.
CEO Dhrupad Trivedi noted that “A10 sits at a critical control point at the intersection of performance and security,” with security-led revenue now accounting for two-thirds of the mix. The risk: a trailing P/E near 44x leaves little room for execution stumbles, and component supply and tariff exposure linger. Still, profitable AI-infrastructure exposure with a dividend is a rare combo under $30. A low share price alone isn’t a thesis.
The Bottom Line
What ultimately matters is the underlying business, the trajectory of margins, and the durability of demand, not the sticker price alone. These three names each tap into rapid digitalization and AI-driven security spending, but every thesis carries real risk. Do your own research, size positions accordingly, and let the fundamentals drive the decision.
