How Atsign Technology Prevents Cyberattacks

Learn how the atPlatform™ and NoPorts™ solve a variety of attack scenarios targeting data and credentials.

Given the continued rise in cyberattacks1, developing products and services that have security built-in is “…an essential component of responsible cybersecurity.”2

Atsign’s proactive, security-first approach minimizes the risk of data breaches, improves customer trust, and significantly reduces both the long-term costs associated with monitoring and prevention tools and of repairing systems (and reputations) post-incident.

Let’s examine how Atsign’s unique technology addresses some of the top cyber threats.

Interception Attacks, such as Eavesdropping, Man-in-the-Middle, and HNDL (harvest now, decrypt later)
DoS and DDoS Attacks
Phishing
Password Attack
SQL Injection
Birthday Attack
Drive-by Attack
What it is
These all start with intercepting data, whether it's to steal sensitive information (Eavesdropping), to get between two parites to access or alter data (Man-in-the-Middle), or to steal encrypted data today with the intention of decrypting it in the future using quantum computing (HNDL-harvest now, decrypt later).
Overwhelming a system with traffic to prevent legitimate access.
Deceiving people into revealing personal information through fraudulent communication.
Methods to gain unauthorized access using stolen or guessed passwords.
Exploiting vulnerabilities in web applications to manipulate databases
Mathematical exploit to crack cryptographic hashes faster than brute force.
Downloading malicious code onto someone’s device without their knowledge, usually via a compromised website.
How Atsign solves
Data is end-to-end encrypted, with keys that are cut and kept at the edge. The communication is peer-to-peer, so there’s no central place to intercept transmissions, which prevents these tactics.
Decentralized architecture enhances resilience against these attacks. Allowing application backends to retain closed ports means that even if an atServer goes down, enterprise services can remain operational within their private networks.
A privacy-first approach, along with using cryptographic keys for authentication, significantly reduces the risk of phishing. Minimizing data exposure and eliminating usernames and passwords makes it harder for phishers to succeed.
Cryptographic authentication means that passwords are not necessary, making brute-force and credential stuffing attacks ineffective.
Each atSign’s data is stored separately, and more importantly, Atsign does not use SQL.
Atsign employs cryptographic algorithms with proven resistance to birthday attacks. These algorithms are designed to minimize the probability of hash collisions, making it difficult for attackers to exploit this vulnerability.
Atsign’s APKAM, our Application Permission and Key Management system, limits application access to only the resources they absolutely need, minimizing the impact of successful drive-by attacks that may attempt to install malware.

Whether you’re building on the atPlatform or integrating Atsign’s NoPorts into your existing infrastructure, you’re eliminating attack surfaces, strengthening resilience, and future-proofing your systems against evolving cyber threats.
