Top Security Startups in 2027

SAFE enables an organization to predict cyber breaches in their environment while contextually aggregating signals from existing cybersecurity products, external threat intelligence, and business context. This data is fed into a supervised Machine Learning Bayesian Network-based breach likelihood prediction engine that gives scores, prioritized actionable insights, and the $ Value Risk the organization is facing.

WAIL is building the execution intelligence and runtime control layer for production AI systems. AI systems are becoming more autonomous, distributed, and difficult to control in real time. Traditional observability can tell teams what happened after an execution fails. WAIL is being built to understand how execution normally behaves, detect when that behavior begins to deviate, and enable control while execution is still in progress. Today, WAIL provides runtime observability and control capabilities including behavioral baselines, anomaly and drift detection, retry and reroute actions, governance, recovery verification, and cryptographically signed execution evidence. We are now expanding WAIL toward predictive execution control: learning the behavioral DNA of AI and agent execution, identifying emerging execution failures before they occur, enabling preemptive intervention, and verifying whether recovery actually worked. Our long-term goal is to make AI execution measurable, predictable, controllable, and auditable — from individual model calls to increasingly autonomous agent systems. WAIL is an early-stage company. We are building both the technology and the go-to-market motion from the ground up, and we are looking for people who want to help shape what this category becomes.

Longwave is on a mission to transform MSPs (i.e., outsourced IT firms) into AI solutions providers. Our unique insight is that MSPs will be the final mile of distribution to introduce AI products to small- and medium-sized businesses in every industry across the globe. We raised our pre-seed round from three VC firms earlier this year (Comma Capital, Dria Ventures, and Top Down Ventures) and have several years of runway. Our co-founders (CEO, CTO) bring big-tech experience and hypergrowth mentality to the world of MSPs.

We determine the organisation's current state and targets a desired future state that reduces cyber risks to provide better protection from cyber-attacks. The purpose is to identify gaps in organization and prepare an action plan for improvement. The process provides organisations with clear insights into their cybersecurity weaknesses and strengths in order to improve their current security posture or benchmark against best practices in the industry.

Mentor18 is the enterprise zero-trust transit gateway built to secure, govern, and notarize autonomous AI agents, LLM pipelines, and multi-cloud APIs at the network wire. THE HARD PROBLEM WE SOLVE: As Global 2000 enterprises, health systems, and government agencies deploy generative AI and autonomous agents, CISOs and risk committees are slamming the brakes. The fear of IP leakage, regulatory violations (HIPAA, SEC/FINRA, FedRAMP, EU AI Act), and un-audited agentic actions has created a multi-billion dollar enterprise bottleneck. OUR INNOVATION & CORE PHYSICS: We engineered Enterprise Gateway by Mentor18—a 100% agentless, model-agnostic transit gateway operating at wire speed: • In-RAM Deep Packet Inspection (<1.5 ms latency): Real-time zero-trust enforcement in volatile RAM with guaranteed Zero Data Retention (payload_bytes_stored: 0). • Sovereign WORM Audit Receipts (m18.receipt.v1): Generates court-admissible, cryptographically sealed audit proofs for every AI prompt, API call, and agent action on Day 1. • 163 Enterprise Controls Across 15 Verticals: Pre-built compliance physics covering Healthcare, Financial Services (SOX 404/PCI-DSS), Defense, and Critical Infrastructure. COMMERCIAL STATUS & ECOSYSTEM: • Production-deployed multi-cloud architecture (AWS PrivateLink, Google Cloud, Microsoft Azure). • Published live on the Microsoft Commercial Marketplace with 100% Azure MACC drawdown eligibility. • OpenAI Registered Partner. • US Federal SAM.gov registered (CAGE: 26ZK8, UEI: X6LVYWKLDME7). WHO WE ARE LOOKING FOR (REVENUE & CLOSERS ONLY): Our technology is 100% built and live in production. We are exclusively hiring proven Deal Closers, Revenue Drivers, and Rainmakers: • Founding Enterprise Account Executives (closing Fortune 1000 CISOs & CIOs). • B2G & Defense Rainmakers (navigating federal procurement, SLED, and prime contractors). • Commercial Sales & GTM Growth Leaders (driving enterprise pipeline & revenue).

Every modern company now runs on far more machine identities than human ones: service accounts, API keys, tokens, OAuth apps, secrets and, increasingly, AI agents. These non-human identities (NHIs) hold privileged access to production systems, yet they are rarely owned, rotated or monitored. That gap is where today's breaches start. StackGuard is a remediation-first NHI security platform. We help security and engineering teams: - Discover every NHI across cloud, code, SaaS, chat tools, vaults and directory services - Govern them with ownership attribution, risk-based severity and policy - Remediate risky identities and leaked secrets, not just alert on them We cover non-human identities, AI agents, directory services (Active Directory) and cloud workloads, with integrations across AWS, Google, Microsoft, GitHub, GitLab, Atlassian, Databricks, Slack, Salesforce, OpenAI, Okta-style IdPs like Auth0, Cloudflare, Datadog, HCP Terraform, Notion and more. StackGuard deploys fully on-prem as a sovereign platform: no identities or vulnerabilities ever leave the customer's environment, which makes us a fit for regulated enterprises. We're a seed-funded team founded by offensive security researchers with Hall of Fame recognitions from Google, Netflix and NASA, and alumni of Astra Security and PingSafe/SentinelOne. StackGuard is part of the NVIDIA Inception program and listed on Gartner Peer Insights. We're building in New Delhi and looking for engineers who want to solve hard identity-security problems at the intersection of cloud, code and AI.

At SiegePal, we're building an AI-powered cybersecurity platform that helps businesses identify vulnerabilities, understand security risks, and protect their applications and cloud infrastructure more efficiently. Our platform brings together specialized AI agents that work alongside security professionals to automate complex cybersecurity tasks, from reconnaissance and vulnerability scanning to penetration testing, threat analysis, and compliance reporting. By integrating existing security tools with large language models (LLMs), we aim to reduce repetitive manual work and make advanced security capabilities more accessible. **The hard problems we're solving:** - **AI agent orchestration:** Building a system where multiple specialized AI agents can collaborate, share context, and execute complex security workflows reliably. - **Security automation:** Turning fragmented security tools and manual processes into coordinated workflows that identify, prioritize, and help remediate vulnerabilities. - **Cloud security at scale:** Integrating with AWS, Azure, and Google Cloud to assess infrastructure, detect misconfigurations, and manage security risks across complex environments. - **Safe AI execution:** Giving AI agents the ability to interact with real systems while maintaining strict permissions, isolation, auditability, and human oversight. - **Actionable security intelligence:** Transforming large volumes of technical findings into clear recommendations that engineering teams can act on. Alongside our platform development, we deliver cybersecurity and AI engineering services for businesses operating in cloud and regulated environments. We're a small, engineering-driven team working at the intersection of cybersecurity, artificial intelligence, and cloud infrastructure. Our developers tackle real technical challenges, experiment with emerging technologies, and have the opportunity to shape a product from its early stages.
