No need to flee, it’s totally free


    In today’s digital world, security is one of the most important aspects for companies and individuals. The vast majority of our activity on the Internet happens through websites, services and networks dependent on trust. 

    This trust must be established quickly, without disruption or frustration when it comes to browsing securely online. That’s why DANE (DNS-based Authentication of Named Entities) stands out as a revolutionary solution – empowering users with an efficient way to establish secure connections while remaining private and untraceable. 

    With its array of benefits such as improved authentication methods, faster internet speeds and better connection protection, it’s easy to see why so many are embracing this new technology that promises true ownership over digital identities in the near future. Read on to understand more about how DANE works and what advantages it offers!

    What is DANE?

    DANE is a security protocol that uses the Domain Name System Security Extensions (DNSSEC) to verify the authenticity of digital certificates used in online communication. Digital certificates are used to establish trust between two parties and to ensure the confidentiality and integrity of data transmitted over the internet. They are commonly used in HTTPS, the protocol used to secure online communication between web browsers and servers.

    However, digital certificates can be compromised, leading to security breaches and data loss. DANE addresses this issue by using DNSSEC to store and distribute digital certificate information securely. This allows online communication to be authenticated and encrypted without the need for traditional Certificate Authorities (CAs), which have come under scrutiny for their vulnerabilities.

    How does DANE work?

    DANE works by storing digital certificate information in DNS records, which are authenticated using DNSSEC. This means that the authenticity of the certificate can be verified without relying on CAs. The following steps outline the process of establishing a secure connection using DANE:

    1. The client sends a DNS query for the domain name of the server it wants to connect to.

    2. The DNS server responds with the IP address of the server and the DANE record associated with the domain name.

    3. The client verifies the authenticity of the DANE record using DNSSEC.

    4. The DANE record contains the digital certificate information, including the public key and the certificate authority (CA) that issued the certificate.

    5. The client verifies the authenticity of the certificate using the public key stored in the DANE record.

    6. The client establishes a secure connection with the server using the authenticated digital certificate.

    Why is DANE the future of internet security and trust?

    DANE offers several advantages over traditional digital certificate authentication methods:

    1. Improved security

    DANE eliminates the need for centralized CAs, which have come under scrutiny for their vulnerabilities. This means that DANE is less susceptible to security breaches and data loss.

    2. Increased trust

    DANE provides a more transparent and verifiable way of authenticating digital certificates, which increases trust between two parties.

    3. Better control

    DANE gives domain owners more control over their digital certificates, allowing them to store and distribute certificate information securely without relying on third-party CAs.

    4. Reduced costs

    DANE eliminates the need for domain owners to purchase digital certificates from third-party CAs, which can be expensive.

    Examples of DANE in action

    DANE is still a relatively new technology, but it is gaining traction in the tech industry. Here are some examples of DANE being used in the real world:


    In 2015, Google announced that it had implemented DANE for its Gmail service. This means that users can verify the authenticity of the digital certificates used to secure their email communication without relying on third-party CAs.


    Cloudflare, a content delivery network and security provider, offers DANE as a feature for its customers. This allows website owners to secure their online communication using DANE without relying on traditional CAs.


    Cisco, a leading provider of networking equipment, has implemented DANE in its IOS and IOS-XE software. This allows Cisco customers to authenticate digital certificates using DANE without relying on third-party CAs.


    DANE offers a promising solution to the security and trust issues that have plagued online communication for years. By eliminating the need for centralized CAs and using DNSSEC to store and distribute digital certificate information securely, DANE provides a more transparent, verifiable, and secure way of authenticating online communication. As more companies and organizations adopt DANE, it has the potential to become the new standard for internet security and trust.

    However, DANE is not without its limitations. One major challenge is the lack of widespread adoption, as it requires changes to DNS infrastructure and web browser support. Additionally, DANE does not provide protection against all types of attacks, such as man-in-the-middle attacks that occur before the DNS lookup.

    Despite these challenges, DANE is an exciting development in the world of internet security and has the potential to revolutionize the way we authenticate online communication. As more companies and organizations adopt DANE, we can look forward to a more secure and trustworthy internet for everyone.
