What are the top unmet needs or pain points in cloud security that startups could realistically address today?

Misconfiguration vulnerabilities represent the most critical unmet need, causing over 99% of cloud breaches through improperly configured storage buckets, IAM roles, and network ACLs.

Visibility gaps across multi-cloud, container, and serverless environments plague enterprises, with existing CSPM and CNAPP tools covering only 60% of cloud assets. Security teams struggle with blind spots that leave critical infrastructure unmonitored and unprotected.

Alert fatigue from disconnected security tools creates dangerous operational inefficiencies. Runtime context correlation between CWPP, CSPM, and identity events remains immature, leading to either ignored critical alerts or wasted time investigating false positives. Data protection in use represents another major gap—while data at rest and in transit are well-protected, data actively being processed in memory remains largely unencrypted, with confidential computing adoption below 10% despite increasing AI workload demands.

Identity and access compromises affect 68% of cloud attacks through stolen credentials or misused keys, yet zero-trust adoption remains under 30% in mid-market firms. SMEs particularly struggle with understanding shared responsibility models, leading to dangerous gaps in encryption, patching, and compliance management.

What are the most common reasons existing cloud security solutions fail or fall short for enterprises and SMEs?

Partial coverage represents the primary failure mode, with point solutions addressing only one or two security domains while leaving critical gaps in protection.

CSPM tools catch misconfigurations but miss runtime threats, while CWPP solutions monitor workloads but lack configuration context. This fragmented approach forces security teams to manage multiple disconnected consoles, preventing effective correlation of network, identity, and workload telemetry for comprehensive threat detection.

Manual processes create dangerous bottlenecks in incident response and vulnerability management. High reliance on human triage leads to slow response times and unpatched vulnerabilities, while security teams struggle to prioritize alerts effectively across multiple tools. Vendor lock-in through proprietary agents and APIs creates integration challenges, particularly for multi-cloud customers who face tool fragmentation across AWS, Azure, and GCP environments.

Overcomplex pricing models with unpredictable usage-based billing deter full adoption, leading organizations to disable critical features to control costs. SMEs particularly struggle with solutions designed for enterprises, lacking the expertise and resources to properly configure and maintain sophisticated security tools.

Which recent startups are gaining traction in cloud security, what funding rounds have they closed, and what problems are they solving?

How do cloud providers' native security tools influence or constrain startup opportunities in this space?

AWS, Azure, and GCP offer basic CSPM, IAM, and encryption capabilities but lack unified multi-cloud visibility and advanced threat correlation, creating significant opportunities for third-party solutions.

Cloud providers' native tools create constraints through proprietary APIs, vendor-specific agent requirements, and limited cross-cloud integration capabilities. However, these limitations simultaneously create startup opportunities—companies that deeply integrate with provider telemetry while offering agentless deployment models and cross-cloud abstraction layers can capture substantial market value.

Native tools typically excel at infrastructure-level security but fall short in application-layer protection, runtime context correlation, and advanced AI-driven analytics. Startups succeed by filling these gaps with specialized solutions that complement rather than compete directly with provider offerings, often leveraging cloud provider APIs and marketplaces for distribution advantage.

The shared responsibility model creates natural boundaries where startups can add value above the infrastructure layer, particularly in data protection, application security, and compliance automation. Smart startups position themselves as cloud-agnostic solutions that enhance rather than replace native security controls.
