Are Electronic Signatures Secure?

8th Feb, 2023

As the world becomes increasingly digital, more and more businesses are turning to electronic signatures to streamline their processes, reduce their reliance on paper and to increase their sustainability credentials. However, some companies may be hesitant to adopt electronic signatures due to concerns about security. As the business world evolves, security is becoming more and more imporant, from security on site to secure elctronic signatures, it is a vital component for any business. Here at E-Sign we understand these concerns and want to assure users that electronic signatures are safe and secure to use.

In this blog, we examine the various features that make electronic signatures secure and look at how our solution measures up against the rest.

Digital Certificates

One of the most important security features of electronic signatures is digital certificates. A digital certificate is a type of electronic document that contains information about the identity of the person or organisation that signed the document. This information is verified by a trusted third-party known as a certificate authority (CA). The CA verifies the identity of the signer and issues a digital certificate that contains the signer’s public key. This public key can then be used to verify the authenticity of the signature.


Another key security measure for electronic signatures is the use of encryption. Encryption is a process that is used to scramble data so that it can only be read by the person or organisation that has the decryption key. When a document is signed electronically, the signature is encrypted using the signer’s private key. This ensures that the signature can only be verified by someone who has the signer’s public key.

Our Electronic Signature Security Standards 

We are a secure document management contract automation company, and our E-Sign solution is trusted by nations, governments, businesses, healthcare and education providers globally.


  1. Our Data is Hosted in the UK 

Our network infrastructure uses energy efficient servers housed in independent data centres. Unlike other providers, we host data in the UK – meaning that your data isn’t being sent to servers in the USA or other parts of the world during transactions. This is especially important to organisations such as the NHS, who trust us to send their data securely, with various trusts awarding us ‘preferred supplier’ status and our product has approved government status.


  1. Security Protocols and Tamper-Evident Features

We employ various security protocols such as Secure Socket Layer (SSL) and Transport Layer Security (TLS) to encrypt data and protect it from cyber-attacks. In addition, we have built-in tamper-evident features that allow the signer and the recipient to detect any unauthorised changes to the document after it has been signed. This helps to ensure that the document is not tampered with after it has been signed.


  1. GDPR Compliant

We are fully GDPR compliant, and all the data is stored in highly secure servers with regular backups. This ensures that all electronic signatures are fully compliant with all regulatory requirements. We are accredited to ISO 27001, ISO 9001, PSN and Cyber essentials standards.


  1. Flexible and easily integrated with other software and workflows

Finally, our powerful trademarked, proprietary software is flexible, allowing easy integration with your existing ecosystem. Our committed team will always work to map your business requirements and find a bespoke solution for your needs.


In conclusion, electronic signatures are safe and secure to use. The use of digital certificates, encryption, and tamper-evident features, along with various security protocols, ensures that electronic signatures are just as valid, in fact more secure than traditional signatures. At E-Sign, we are committed to providing our clients with the highest level of security and compliance, so you can feel confident in your use of electronic signatures to create efficiencies across your organisation. That’s why we call our approach “secure thinking.”
