How CISOs Will Evaluate DSPM in 2026: 13 New Buying Criteria for Security Leaders
Data Security Posture Management (DSPM) has quickly become part of mainstream security, gaining ground on older solutions and newer categories like XDR and SSE. Beneath the hype, most security leaders share the same frustration: too many products promise results but simply can't deliver in the messy, large-scale settings that enterprises actually have. The DSPM market is expected to jump from $1.86B in 2024 to $22.5B by 2033, giving buyers more choice - and greater pressure - to demand what really sets a solution apart for the coming years.
Instead of letting vendors dictate the RFP, what if CISOs led the process themselves? Fast-forward to 2026 and the checklist a CISO uses to evaluate DSPM solutions barely resembles the checklists of the past. Here are the 12 criteria everyone should insist on - criteria most vendors would rather you ignore, but industry leaders like Sentra are happy to highlight.
Why Legacy DSPM Evaluation Fails Modern CISOs
Traditional DSPM/DCAP evaluations were all about ticking off feature boxes: Can it scan S3 buckets? Show file types? But most CISO I meet point to poor data visibility as their biggest vulnerability. It's already obvious that today’s fragmented, agent-heavy tools aren’t cutting it.
So, what’s changed for 2026? Massive data volumes, new unstructured formats like chat logs or AI training sets, and rapid cloud adoption mean security leaders now need a different class of protection.
The right platform:
- Works without agents, everywhere you operate
- Focuses on bringing real, risk-based context - not just adding more alerts
- Automates compliance and fixes identity/data governance gaps
- Manages both structured and unstructured data across the whole organization
Old evaluation checklists don’t come close. It’s time to update yours.
The 13 DSPM Buying Criteria Vendors Hope You Don’t Ask
Here’s what should be at the heart of every modern assessment, especially for 2026:
- Is the platform truly agentless, everywhere? Agent-based designs slow you down and block coverage. The best solutions set up in minutes, with absolutely no agents - across SaaS, IaaS, or on-premises and will always discover any unknown and shadow data
- Does it operate fully in-environment? Your data needs to stay in your cloud or region - not copied elsewhere for analysis. In-environment processing guards privacy, simplifies compliance, and matches global regulations (Cloud Security Alliance).
- Can it accurately classify unstructured data (>98% accuracy)? Most tools stumble outside of databases. Insist on AI-powered classification that understands language, context, and sensitivity. This covers everything from PDF files to Zoom recordings to LLM training data.
- How does it handle petabyte-scale scanning and will it break the bank? Legacy options get expensive as data grows. You need tools that can scan quickly and stay cost-effective across multi-cloud and hybrid environments at massive scale.
- Does it unify data and identity governance? Very few platforms support both human and machine identities - especially for service accounts or access across clouds. Only end-to-end coverage breaks down barriers between IT, business, and security.
- Can it surface business-contextualized risk insights? You need more than technical vulnerability. Leading platforms map sensitive data by its business importance and risk, making it easier to prioritize and take action.
- Is deployment frictionless and multi-cloud native? DSPM should work natively in AWS, Azure, GCP, and SaaS, no complicated integrations required. Insist on fast, simple onboarding.
- Does it offer full remediation workflow automation? It’s not enough to raise the alarm. You want exposures fixed automatically, at scale, without manual effort.
- Does this fit within my Data Security Ecosystem? Choose only platforms that integrate and enrich your current data governance stack so every tool operates from the same source of truth without adding operational overhead.
- Are compliance and security controls bridged in a unified dashboard? No more switching between tools. Choose platforms where compliance and risk data are combined into a single view for GRC and SecOps.
- Does it support business-driven data discovery (e.g., by project, region, or owner)? You need dynamic views tied to business needs, helping cloud initiatives move faster without adding risk, so security can become a business enabler.
- What’s the track record on customer outcomes at scale? Actual results in complex, high-volume settings matter more than demo promises. Look for real stories from large organizations.
- How is pricing structured for future growth? Beware of pricing that seems low until your data doubles. Look for clear, usage-based models so expansion won’t bring hidden costs.
Agentless, In-Environment Power: Why It’s the New Gold Standard
Agentless, in-environment architecture removes hassles with endpoint installs, connectors, and worries about where your data goes. Gartner has highlighted that this approach reduces regulatory headaches and enables fast onboarding. As organizations keep adding new cloud and hybrid systems, only these platforms can truly scale for global teams and strict requirements.
Sentra’s platform keeps all processing inside your environment. There’s no need to export your data; offering peace of mind for privacy, sovereignty, and speed. With regulations increasing everywhere, this approach isn’t just helpful; it’s essential.
Classification Accuracy and Petabyte-Scale Efficiency: The Must-Haves for 2026
Unstructured data is growing fast, and workloads are now more diverse than ever. The difference between basic scanning and real, AI-driven classification is often the difference between protecting your company or ending up on the breach list. Leading platforms, including Sentra, deliver over 95% classification accuracy by using large language models and in-house methods across both structured and unstructured data.
Why is speed and scale so important? Old-school solutions were built with smaller data volumes in mind. Today, DSPM platforms must quickly and affordably identify and secure data in vast environments. Sentra’s scanning is both fast and affordable, keeping up as your data grows.

Don’t Settle: Redefining Best-in-Class DSPM Buying Criteria for 2026
Many vendors are still only comfortable offering the basics, but the demands facing CISOs today are anything but basic. Combining identity and data governance, multi-cloud support that works out of the box, and risk insights mapped to real business needs - these are the essential elements for protecting today’s and tomorrow’s data. If a solution doesn’t check all 12 boxes, you’re already limiting your security program before you start.

Conclusion
With AI further accelerating data growth, security teams can’t afford to settle for legacy features or generic checklists. By insisting on meaningful criteria - true agentless design, in-environment processing, precise AI-driven classification, scalable affordability, and business-first integration - CISOs set a higher standard for both their own organizations and the wider industry.
