Organizations are generating, capturing, and storing huge volumes of data, both structured and unstructured, at cloud SaaS endpoints and within an enterprise’s premises. Without categorization, this data landscape is vulnerable to excessive exposure, inappropriate use, or leakage.
Sensitive data (including PII data, financial data, Intellectual property data, and regulated data) is at risk. Now, through today’s data discovery and classification tools, we can help companies discover, classify, label, and protect their sensitive data, while guiding compliance to GDPR, HIPAA, PCI DSS, SOX, and NIS2.
In 2026, the focus is on AI-ready security with AI-ready features, real-time risk context, auto-remediation and hybrid cloud scope.
Lepide’s Perspective: Why Data Classification Projects Fail
Here are some of the most common reasons why data classification projects fail:
- Massive Volumes of Existing Data: When searching for large quantities of existing data spread throughout file servers, SaaS applications, and cloud storage systems it can take significant amounts of time and resources to identify and classify the initial data set. This often surprises many organizations.
- Unstructured Data Complexity: Sensitive/protected or personally identifiable data is often stored in unstructured ways like bulk shares and e-mail PDF captures, and there is significant challenge in accurately classifying data.
- Visibility Gaps Across Hybrid Environments: Today, companies are storing data in clouds, 365 SaaS applications, on-premises environments, etc. Some solutions may not have the capability to deliver unified visibility across all these repositories.
- Lack of Continuous Classification: Because of the sheer time it takes to fully scan and classify sensitive data across the average organization, continuous scanning at the point of creation is a necessity. Classification must keep pace with the growth of the number of files users, cloud services, and AI techniques.
How to Choose the Best Data Classification Tool for Your Business
To select a data classification tool that fits your security and commercial objectives, you will need to assess features, scalability, compliance support, and practical use.
1. Identify your Data Environment
Few companies have simple environments; in many cases, companies run a hybrid environment that includes file servers, SaaS applications, cloud storage, and databases. An adequate classification platform would manage:
- Structured and unstructured data
- Cloud and on-premises repositories
- SaaS applications
- Endpoint visibility
- Multi-cloud environments
Organizations with hybrid environments should look for a portal that will provide one centralized location where all the data sources can be overseen.
2. Prioritize Real-Time Risk Detection
Today’s threats change quickly; because of this, access and insider threats unmask data by AI. There are several mechanisms that integrate classification with DSPM and DLP. Choose the tools that provide:
- Real-time monitoring
- Excessive permission detection
- User behaviour analytics
- Automated remediation
- Abnormal access alerts
3. Check for Automated Classification
Manual classification is slow, inconsistent, and difficult to scale. Automated classification significantly reduces administrative overhead by improving classification accuracy. Modern solutions use:
- AI-powered discover
- Pattern matching
- Behavioural Analytics
- Labeling with context awareness
4. Evaluate Compliance Support
The ideal solution should make compliance activities easier by assisting with:
- Recognizing Regulated Information
- Create Reports for Audits
- Monitor Permissions for Access
- Identify Policy Violations
- Implement policies for protection and retention.
GDPR, HIPAA, PCI DSS, SOX, NIS 2, and CCPA should be looked up in the pre-built compliance templates.
5. Examine Ease of Deployment
Some corporate platforms can be operational in a few days, but others require a dedicated team and several months of implementation. Mid-sized businesses tend to choose solutions that are easy to manage and can be deployed more rapidly.
- Complexity of Deployment
- Curve of Learning
- Scalability
- Overhead in Administration
6. Assess AI and Gen AI Security Capabilities
Data classification is now a fundamental component of AI governance as companies use Copilot, ChatGPT, and generative AI. At the moment, the top tools offer:
- Monitoring AI SaaS usage in real time
- AI-sensitive data security based on browsers
- Labeling and Examining AI remarks
What Most Buyers Get Wrong
Most organisations approach data security from the data outward. They focus on discovering sensitive files, classifying information, and monitoring where data lives. While important, this data-centric approach often ignores where most real-world threats actually begin: identities and permissions.
Users, groups, service accounts, inherited permissions, and misconfigured access are what ultimately determine who can access sensitive information and what they can do with it. This creates what Lepide describes as the “Identity Data Disconnect” – a gap between understanding where sensitive data exists and understanding which identities can actually access it. Without connecting these two worlds together, organisations struggle to prioritise risk effectively or reduce exposure at scale.
To close this gap, organisations need to start with identities first. That means understanding who their users are, how permissions are assigned, where privilege has accumulated over time, and how access is changing across the environment. Once this visibility exists, it can then be linked directly to sensitive data to provide meaningful risk context. Instead of simply knowing that sensitive data exists somewhere in the environment, security teams can identify which users have unnecessary access, where permissions sprawl exists, and which exposures present the greatest risk to the organisation. This identity-first approach provides a far more operational and actionable foundation for modern data security.

Lepide’s Evaluation Perspective
Organizations are interested in moving from standalone discovery tools to integrated platforms with data classification combined with access governance, behavioral monitoring, and AI-enabled security controls due to the growing shifts in data security needs and expectations. The extended evaluation criteria included hybrid visibility across on-premises and cloud, audit and risk detection in real-time, scalability for enterprise scale, permission analysis and access governance, and compliance reporting.
In evaluating the best classification tools for 2026, Lepide focused not only on discovery accuracy but also on truly understanding the Identity-Data Disconnect, gradually incorporating data security into a unified platform.

How AI and Copilot Are Changing Data Classification
The concept of data classification is evolving in the current security model as the AI platform economy develops (see Microsoft Copilot, ChatGPT, etc.).
With this new mindset, businesses can no longer approach data classification as only a compliance-related activity, in which the organization just locates all the sensitive files.
AI does not introduce novel permission vulnerabilities; it rather enhances the already existing difficulties of permission elevation and oversharing at a new speed. Doing so has technically led organizations to expand the scope of their definition of what perfect data classification includes.
It’s not just about revealing sensitive content, but security needs to know who will be viewing this material, to identify where the permission begins to occur, and how AI systems may use the identified data in a hybrid context.
Yet, as AI is deployed in the day-to-day, classification should become a core part of AI governance, insider threat prevention, and other broader information security strategies.
Conclusion
Classifying data has long moved beyond assigning labels; it looks like this year, companies will rely more on platforms that provide discovery governance compliance, access intelligence, DLP & AI security features as a single integrated solution.
Organizations with over-complex file systems have historically purchased Varonis, while privacy-conscious organizations lean toward BigID.
Yet, other companies coming after the fast deployments, hybrid visibility, simplified compliance reporting, and permission analysis might be under the comfort of Lepide.
Finally, the best classification tool will always depend on your infrastructure, compliance requirements, security maturity level, and long-term governance strategy.
