What are the biggest cybersecurity pain points in enterprises today that zero trust could help solve but currently doesn't?

Enterprise security teams face five critical challenges that current zero trust solutions inadequately address, creating substantial market opportunities for innovative startups.

Policy sprawl represents the most significant unresolved pain point. Organizations struggle to manage thousands of granular access policies across firewalls, cloud ACLs, and endpoint agents, leading to inconsistent enforcement and security drift. Current solutions lack unified policy orchestration engines that can translate business intent into technical controls across heterogeneous environments.

Dynamic authorization complexity compounds this challenge. While zero trust mandates context-based access decisions, enterprises lack real-time behavioral analytics integration. Most solutions rely on static policies rather than continuous risk assessment incorporating user behavior, device posture, and threat intelligence. This creates blind spots where sophisticated attackers can exploit legitimate access patterns.

Legacy and edge environment integration remains severely limited. OT/ICS systems and resource-constrained IoT devices cannot support modern identity APIs or continuous attestation agents. Current zero trust architectures designed for cloud-native workloads fail to extend seamlessly to safety-critical industrial environments, leaving critical infrastructure exposed.

Holistic visibility gaps persist despite microsegmentation investments. Organizations lack unified dashboards showing trust relationships across hybrid IT/OT environments. Shadow IT, fragmented security toolsets, and incompatible telemetry formats prevent comprehensive risk assessment and incident response coordination.

Which specific zero trust problems are actively being worked on by startups, and what technologies are they using?

Leading startups focus on four core technology approaches to address the most pressing zero trust implementation challenges.

Agentless microsegmentation represents the largest funding category. Zero Networks ($55M Series C) uses machine learning to analyze traffic flows and automatically generate network policies without deploying endpoint agents. Their technology maps east-west traffic patterns and creates identity-based segmentation rules that work with existing network infrastructure. Elisity ($37M Series B) applies similar principles specifically to converged IT/OT environments, enabling microsegmentation for industrial protocols like Modbus and DNP3.

Continuous privileged access management solutions move beyond traditional password vaulting. StrongDM ($34M Series C) implements real-time, context-aware PAM that adjusts access permissions per request based on user behavior, device trust, and resource sensitivity. Their platform intercepts and inspects privileged sessions in real-time, providing granular audit trails and automated policy enforcement.

Identity-centric OT security addresses industrial environment challenges. Xage Security ($20M growth round) deploys a distributed trust mesh using blockchain-anchored identity verification for hybrid IT/OT/cloud networks. Their technology enables secure communication between industrial control systems and enterprise networks without compromising operational technology requirements.

Zero trust networking for cloud applications tackles multi-cloud complexity. NetFoundry ($12M Series A) provides software-defined networking with embedded zero trust controls, enabling secure application-to-application communication across cloud boundaries. Their approach eliminates the need for traditional VPNs while providing granular access control for distributed applications.

Which major challenges in zero trust implementation remain unsolved, and why are they hard to address right now?

Four fundamental challenges continue to resist practical solutions due to technical complexity and resource constraints.

Policy management scalability becomes exponentially difficult as organizations grow. Managing millions of dynamic access policies across heterogeneous environments requires sophisticated orchestration engines that don't exist. The challenge stems from the combinatorial explosion of users, devices, applications, and contexts that need individual policy definitions. Current solutions rely on manual policy creation and static rule sets that cannot adapt to changing business requirements or threat landscapes.

Legacy system integration faces inherent architectural limitations. Industrial control systems and embedded devices lack computational resources for modern identity protocols and continuous monitoring agents. These systems often run proprietary protocols designed for air-gapped environments, making retrofitting with zero trust capabilities technically infeasible without compromising operational safety and reliability.

Behavioral analytics integration requires massive data processing capabilities and sophisticated machine learning models. Real-time analysis of user behavior, device posture, and threat intelligence across enterprise environments generates petabytes of telemetry data. Building AI models that can accurately distinguish between legitimate and malicious activity while minimizing false positives demands specialized expertise and computational resources beyond most organizations' capabilities.

User experience optimization conflicts with security requirements. Strict zero trust controls create friction that drives shadow IT adoption and workaround behaviors. Balancing security effectiveness with productivity requirements requires nuanced understanding of business workflows and user psychology that current solutions cannot adequately address.

What kinds of zero trust use cases are still underserved or completely untapped by current solutions?

Five high-value use cases remain largely unexplored, representing significant market opportunities for specialized startups.

Cross-cloud service trust lacks standardized frameworks for automated policy enforcement. Organizations using multiple cloud providers struggle to maintain consistent security postures across AWS, Azure, and Google Cloud environments. Current solutions provide point-to-point connectivity but cannot dynamically adjust access policies based on cross-cloud resource dependencies and data flows.

Supply chain partner integration presents complex trust federation challenges. B2B collaborations require dynamic access provisioning for external partners while maintaining security boundaries. Existing SAML and OAuth implementations provide authentication but lack fine-grained authorization and continuous trust assessment for third-party access to sensitive resources.

AI/ML model protection represents an emerging frontier with minimal current solutions. Ensuring integrity and provenance of machine learning artifacts across training, validation, and production deployment requires specialized zero trust frameworks. This includes protecting training data, model weights, and inference pipelines from tampering and unauthorized access.

DevOps-embedded zero trust remains nascent outside specialized toolchains. Integrating continuous trust verification into CI/CD pipelines requires zero trust principles to be applied to code repositories, build systems, and deployment environments. Current solutions focus on production runtime security rather than development lifecycle protection.
