9 Cybersecurity Startups to Watch in 2026
Cybersecurity startups raised $12B in 2025. These are the nine companies the sharpest VCs are quietly loading up on before the market catches on.
Key Takeaways
- Cyera, Abnormal, and Island lead the late-stage pack with valuations between $3B and $5B
- AI model security is the hottest new subsector, with HiddenLayer and Lakera raising fast through 2024
- Identity-based attacks drive 68% of breaches (Verizon DBIR), and Silverfort is the protocol-agnostic bet
- SMB cyber finally woke up: Huntress crossed $1.5B at its last round
- Israeli founders (often ex-Unit 8200) lead five of our nine picks. The ecosystem effect is real.
The Cybersecurity Gold Rush Isn't Slowing Down
Cybersecurity startups raised roughly $12 billion in 2025 according to Crunchbase data, a number that would have been laughable a decade ago. The sector is now the most reliably fundable category in venture. Enterprise buyers have no choice, regulators keep tightening the screws, and every new tech wave (cloud, mobile, generative models) opens a fresh attack surface.
The trick isn't deciding whether to pay attention. It's picking the right names before the crowd piles in and prices get silly.
Here's the list we'd actually bet on, built from public funding data, growth signals, and founder pedigree. As of April 2026, based on publicly reported data.
Cyera
What they do: Data security posture management (DSPM). They map every piece of sensitive data across your cloud, figure out who can touch it, and flag what's one misconfiguration away from leaking.
Who: Yotam Segev and Tamar Bar-Ilan, both Israeli Unit 8200 alumni.
Funding: Series D in 2024, roughly $300M at a $3B+ valuation. Backers include Accel, Sequoia, and Coatue.
Why watch: DSPM went from "cute category" to "board-level budget line" in 18 months. Cyera is the clear leader, and the data security TAM is arguably bigger than endpoint.
Abnormal Security
What they do: AI-native email security. They replace legacy secure email gateways by modeling what "normal" communication looks like inside a company and flagging everything that isn't.
Who: Evan Reiser, previously in security at Twitter.
Funding: Series D in 2024, $250M at $5.1B. Reportedly crossed $200M ARR en route.
Why watch: Email is still the number one breach vector, and Abnormal's growth curve is rare. They've roughly doubled ARR every year since Series B. IPO whispers are getting louder.
Island
What they do: The enterprise browser. Instead of bolting security tools onto Chrome, they ship a Chromium-based browser with DLP, access controls, and session recording baked in.
Who: Mike Fey (ex-Symantec, ex-McAfee) and Dan Amiga.
Funding: Series D in 2024, $175M at $4.8B. Backed by Sequoia, Insight, and Coatue.
Why watch: The "browser as the new endpoint" thesis is finally clicking with regulated enterprises and BPOs who need to let contractors work on unmanaged devices. Category-defining, or category-deluding, and we'll know within 24 months.
Huntress
What they do: Managed detection and response built for SMBs and the MSPs that serve them. 24/7 threat hunting without forcing the customer to hire an internal security team.
Who: Kyle Hanslovan, a former NSA offensive hacker.
Funding: Series D in 2024, $150M at a $1.5B valuation. Sapphire Ventures led.
Why watch: The entire SMB cybersecurity market was ignored by vendors chasing only Fortune 500 logos. Huntress bet the other direction, and the billion-plus valuation is the receipt. Expect acquisition pressure or an IPO by 2027.
HiddenLayer
What they do: Security for machine learning models. They detect model theft, adversarial inputs, data poisoning, and prompt injection in production ML systems.
Who: Chris Sestito and Tanner Burns, former security researchers at Cylance.
Funding: Series A in 2023, $50M. M12 (Microsoft's venture arm) led.
Why watch: Every Fortune 500 deploying generative models is about to realize they're attackable in weird new ways. HiddenLayer has a three-year head start on the category and a patent portfolio that matters.
Lakera
What they do: Guardrails for LLM applications. They sit between your app and the model, blocking prompt injection, PII leaks, jailbreaks, and toxic output.
Who: David Haber, Matthias Kraft, and Mateo Rojas-Carulla.
Funding: Series A in 2024, $20M. Atomico led.
Why watch: They built Gandalf, the viral prompt-injection game that became unofficial training data for half the industry. Smaller than HiddenLayer today, but faster on GenAI-specific risk and the brand halo is real.
Silverfort
What they do: Unified identity protection that plugs into any system, including the legacy ones Okta and Microsoft Entra can't reach (service accounts, on-prem apps, OT environments).
Who: Hed Kovetz, Yaron Kassner, and Matan Fattal. Another Israeli founding team.
Funding: Series D in 2023, $116M at roughly $1B. Greenfield Partners, Singtel Innov8, Citi Ventures.
Why watch: According to the Verizon 2024 Data Breach Investigations Report, 68% of breaches involve a human or machine identity. Silverfort's protocol-agnostic approach is a unique wedge into the biggest attack surface in enterprise security.
Drata
What they do: Compliance automation. They continuously monitor SOC 2, ISO 27001, HIPAA, and PCI controls so you're always audit-ready instead of cramming two weeks before an auditor shows up.
Who: Adam Markowitz (previously founded Portfolium) and Daniel Marashlian.
Funding: Series C in 2022, $200M at $2B. GGV, ICONIQ, and Alkeon backed it.
Why watch: SOC 2 shifted from "nice to have" to "can't sell without it" across most of SaaS. Drata's ARR reportedly crossed $100M in 2024. Think of them as the Stripe of compliance: boring, high-margin, and incredibly sticky.
Oligo Security
What they do: Runtime library security. They track which open-source libraries your code actually executes in production and block anomalous behavior, a direct response to the Log4j era of supply-chain vulnerabilities.
Who: Nadav Czerninski, Gal Elbaz, and Avshalom Hilu.
Funding: Series A in 2023, $50M. Lightspeed led.
Why watch: Static SCA tools flag 10,000 vulnerabilities no one has time to triage. Oligo only surfaces the ones actually reachable at runtime, turning a noise problem into a small, actionable ticket queue.
How We'd Actually Screen These
A watchlist is a starting point, not a thesis. The patterns separating Wiz-tier outcomes from the also-rans tend to be boring: founder security pedigree, vertical focus, net revenue retention above 130%, and regulatory tailwinds driving the sale.
That's exactly what Unicorn Screener evaluates, scoring each of these companies across founder quality, traction velocity, and market dynamics. The live Top 50 leaderboard tracks the highest-scored startups screened to date, including the cybersecurity names already in the running. If you're serious about sourcing the next cybersecurity decacorn, it's worth reading which founder traits actually predict startup success and the 7 red flags investors miss until it's too late before writing any checks.
What to Watch in the Back Half of 2026
Three dynamics worth tracking:
- IPO reopening. Abnormal, Island, and Drata have the ARR profile to go public when the window reopens. The first one out will set comps for the entire category.
- AI security M&A. Palo Alto Networks and CrowdStrike will almost certainly acquire in the HiddenLayer / Lakera space before 2027. If you write early-stage AI-sec checks, price that optionality in.
- Identity consolidation. Okta's stumbles opened room for Silverfort-style challengers. Expect either a mega-round or a strategic acquisition in that space.
Past funding rounds don't predict future outcomes, and every listicle is partly a snapshot of vibe. But the nine companies above combine real revenue, real founder pedigree, and real regulatory pull. That's a rarer combination than the sector press coverage suggests.
