Cybersecurity area

Data Security

Data Security protects sensitive data during use, transfer, storage, sharing, and processing across local, cloud, SaaS, and AI scenarios.

Acronym Glossary

This glossary explains acronyms used in this part so the intended security function is clear.

DLP
Data Loss PreventionDetection and control of sensitive data movement to prevent accidental or unauthorized leakage.
HSM
Hardware Security ModuleSpecialized hardware for secure generation, storage, and use of cryptographic keys.

What This Area Covers

Data Security focuses on protecting data wherever it resides: endpoints, servers, databases, cloud, SaaS applications, AI tools, transmission channels, or shared documents. The foundation is knowing which data is sensitive, who can access it, and how it is used.

Why It Matters

Data leakage can result from an attack, user mistake, incorrect sharing, lost device, weak key management, or uncontrolled use of data in AI and analytics. Data Security therefore consists of several layers: classification, DLP, encryption, key management, HSM, tokenization, and data masking. Each layer protects a different part of the data lifecycle.

How To Navigate This Area

Data protection begins with understanding where sensitive data is located, who works with it, which applications and AI tools it enters, and which rules apply to it. The right combination of classification, DLP, encryption, key management, tokenization, masking, and access controls can then be selected.

Technology selection should start with data type, regulation, and usage model. Protecting documents is different from encrypting disks, tokenizing payment data, masking test data, or managing keys in a hybrid cloud. Protection must be technically strong and usable for everyday users.

The technology list below works as a map of the Data Security area. The practical sequence is to name the security problem first, select the closest technology category second, and only then compare relevant vendors. This helps separate similar-sounding solutions and reduces the risk of adding another tool without a clear architectural role.

The schema shows the main inputs, security layers, and outputs of the Data Security area.

Questions To Ask When Selecting A Solution

  • Which data is most sensitive and where is it located?
  • Is the priority leakage prevention, encryption, classification, or anonymization?
  • Does sensitive data enter SaaS applications, collaboration tools, or AI services?
  • How will policies apply across email, cloud, endpoints, and applications?
  • Who manages cryptographic keys and how is their use audited?

How To Use This Section

Each technology page expands one category, explains its architectural role, and lists SecTec portfolio vendors related to that area. The section page is therefore the orientation layer, while the detail pages support concrete mapping to solutions.
