Top 10: Cybersecurity Startups

The field of cybersecurity is never static, with attackers and defenders constantly on the move to gain the upper hand.

This makes it one of the most fast-moving and consequential battlegrounds in modern technology, shaped by an environment where every new connection, integration and automated system quietly expands the potential for attack.

Standing at the AI forefront, as organisations are accelerating their adoption, the traditional idea of a secure perimeter has largely dissolved. In its place sits a fluid, constantly-shifting digital landscape where identity, data and code itself have become the primary targets.

Attackers are adapting just as quickly, armed with AI, exploiting misconfigurations, compromised credentials and supply chain weaknesses with increasing sophistication and speed.

This has placed enormous pressure on security teams, who must now defend systems that evolve faster than legacy tools can meaningfully track. 

In response, a new wave of cybersecurity startups are emerging with radically different approaches, from autonomous defence systems to AI-driven threat detection and zero trust architectures. Together, they are reshaping what modern protection looks like. 

Here, Cyber Magazine explores the Top 10 cybersecurity startups leading that shift.

10. Geordie AI

By securing a US$6.5m seed investment, the organisation explicitly addresses the severe vulnerabilities introduced by autonomous corporate agents.

Its platform focuses on securing and governing AI agents, giving enterprises real-time visibility into agent behaviour, posture and risk, while enabling organisations to scale AI adoption more safely.

9. ProjectDiscovery

• Founded: 2019
• Based in: San Francisco, US
• CEO: Rishiraj Sharma

ProjectDiscovery brilliantly democratises vulnerability management through an exceptionally popular open-source toolchain coupled with an advanced commercial platform.

Supported by US$28m – raising US1.7m in seed fund and US$25m in series A funding — the firm recently launched Neo, a platform that automates vulnerability discovery and validation workflows.

By enabling reproducible findings and improving signal quality, the technology helps security teams reduce false positives and prioritise remediation more effectively across complex environments.

8. Silent Push

• Founded: 2020

• Based in: Reston, United States

• CEO: Ken Bagnall

Recognised on Fast Company’s "World's Most Innovative Companies of 2026" list, Silent Push pioneers the crucial realm of pre-emptive cyber intelligence.

Backed by US$32m in strategic funding, the sophisticated platform identifies emerging threat infrastructure long before debilitating attacks materialise.

The group leverages proprietary Indicators of Future Attack to detect suspicious domains and internet assets that may be leveraged in upcoming campaigns.

This approach helps security teams gain earlier visibility into potential threats and prioritise defensive actions more effectively.

7. Zenity

• Founded: 2020

• Based in: Tel Aviv, Israel

• CEO: Ben Kliger

This visionary enterprise currently dominates the rapidly expanding Artificial Intelligence Security Posture Management sector, commanding US$59.5m in strategic venture funding.

Its platform provides governance and security controls for AI-powered applications, copilots and automations, helping organisations monitor behaviour, enforce policies and reduce risks such as data leakage.

As enterprises expand their use of generative AI, Zenity enables security teams to gain visibility and apply guardrails across complex environments while supporting broader compliance efforts.

6. Oligo Security

• Founded: 2022

• Based in: Tel Aviv, Israel

• CEO: Nadav Czerninski

Delivering vital runtime application security, Oligo Security focuses on improving visibility into vulnerabilities within software dependencies, particularly in open-source components.

The business has successfully secured around US$80m in total capital to safeguard complex application libraries.

Its platform uses Deep Application Inspection (DAI) – runtime analysis to identify which vulnerabilities are actually reachable and exploitable in production – helping teams prioritise remediation efforts more effectively.

By focusing on active code paths rather than unused components, it reduces noise and supports more efficient risk management across modern software supply chains.

5. Zero Networks

• Founded: 2019

• Based in: Tel Aviv, Israel

• CEO: Benny Lakunishok

Zero Networks is a cybersecurity company focused on simplifying microsegmentation and zero-trust security through an automated, identity-driven platform.

Having successfully raised just over US$100m across multiple financing rounds, the company enables organisations to enforce least-privilege access and reduce lateral movement across enterprise environments.

Its platform combines microsegmentation, identity-based controls and zero trust network access to help security teams improve visibility and control over internal traffic while reducing the attack surface in complex IT infrastructures.

4. Oasis Security

• Founded: 2022

• Based in: New York City, US

• CEO: Danny Brickman

Operating at the critical intersection of identity management and artificial intelligence, Oasis Security provides a comprehensive governance platform designed specifically for non-human identities.

The firm recently secured a substantial US$120m Series B financing round, elevating its total funding to US$195m.

As modern corporate infrastructure becomes increasingly dependent upon autonomous systems, the platform effectively mitigates the severe risks associated with unmonitored machine credentials.

The solution meticulously oversees the entire credential lifecycle, deploying dynamic permissions seamlessly.

3. Lakera

• Founded: 2021

• Based in: Zurich, Switzerland

• CEO: David Haber

This trailblazing enterprise specialises in securing large language models and generative artificial intelligence applications against complex, evolving vulnerabilities.

Following immense strategic momentum, the business was acquired by Check Point Software for a highly lucrative US$300m, cementing its status as a vital industry asset.

Lakera’s technology is designed to help organisations improve the security of AI deployments and gain greater control over model behaviour in production environments.

By neutralising sophisticated prompt injection attacks and preventing severe data leakage, the organisation ensures safe, compliant enterprise AI deployments globally.

2. Koi

• Founded: 2024

• Based in: Tel Aviv, Israel

• CEO: Amit Assaraf

Koi is an exceptionally agile firm, which has rapidly emerged as a critical player in securing the modern software layer, ultimately resulting in a high-profile US$400m acquisition by Palo Alto Networks.

The pioneering platform operates as a unified control layer for all incoming software, comprehensively securing extensions, complex code packages and sophisticated artificial intelligence models against systemic vulnerabilities.

Its platform uses automated analysis techniques, including sandboxing, to improve visibility into software behaviour and help security teams detect malicious or vulnerable code earlier in the development and deployment lifecycle.

By proactively addressing immense blind spots that traditional security tools consistently miss, the business actively protects major technology clients. 

1. 7AI

• Founded: 2024

• Based in: Boston, United States

• CEO: Lior Div

Standing as the definitive leader amongst high-growth, non-unicorn cybersecurity startups, this organisation focuses on applying autonomous AI agents to security operations, particularly in alert triage and incident response.

Recently executing the largest Series A funding round in cybersecurity history with a US$130m capital injection, the business commands a robust US$700m valuation.
