When buying PDF and e-signature tools or software, it’s important to familiarize yourself with its security features.

Whether you're a small business or global corporate, software security is one of the most important factors to consider when buying a PDF management tool.

Your teams will work with sensitive and confidential information, be that PDF documents or client contracts. The software you use should eliminate security vulnerabilities like unauthorized access or document tampering. The software should also comply with data handling laws and recognized general best practices.

Here, you will find security features to look for when buying PDF or e-signature software:

  1. digital signatures
  2. LVT timestamp
  3. CCPA compliance
  4. GDPR compliance
  5. TLS encryption
  6. ISO/IEC 27001 accreditation
  7. eIDAS compliance

Digital Signatures

Digital signatures are a very secure type of e-signature. These signatures are verified and authenticated through a specific mathematical algorithm. Both e-signatures and digital signatures are legally binding—check local laws to confirm legal requirements.

LVT Timestamp

A Long Term Validation (LTV) timestamp is a feature that comes with digital signatures. It allows users to authenticate a signature and ensure it hasn’t been tampered with.

CCPA Compliance

The California Consumer Privacy Act (CCPA) covers the rights of consumers living in California, USA. Similar to the GDPR, the CCPA protects both the consumer and their privacy rights.

GDPR Compliance

General Data Protection Regulation (GDPR) is a European Union (EU) law covering privacy and data protection in the EU and the European Economic Area (EEA). The law aims to strengthen EU citizens’ personal data protection rights.

ISO/IEC 27001 Accreditation

ISO/IEC 27001 is an international standard published by the International Organization for Standardization and the International Electrotechnical Commission. The standard focuses on best practices for information security management.

TLS Encryption

Transport Layer Security encryption (TLS) is a special protocol that secures communication between two or more applications over a computer network using encryption.


Electronic Identification, Authentication and Trust Services or eIDAS is an EU regulation. It ensures digital signatures and identification across all EU member states are both secure and standardized.
