Duo’s full-time security team is experienced in running large-scale systems security. We employ the top mobile, app and network security experts. Our researchers and engineers have worked at Fortune 500 companies, government agencies and financial firms.
Duo is founded by CEO Dug Song and CTO Jon Oberheide, two respected pioneers in the security community with a commitment to driving innovation and growth. Learn more about our team.
Duo follows an agile development cycle, releasing updates in hours and days compared to several months and quarters, typical of other two-factor vendors.
There’s no overhead required to keep our application up to date - we send automatic updates to your users’ devices to ensure they have the latest security patches and features. Consider it the end of maintenance windows for your in-house IT support.
Duo builds security into each step of our operations, including customer data handling, code release, upgrades, patch management, security policies and more.
We endeavor to meet compliance standards like PCI DSS, OWASP, ISO 27001, NIST 800 and more. A team of independent third-party auditors regularly audit and review our infrastructure and operations to ensure we’re secure enough to support our customers.
Some two-factor solutions rely on shared secrets to generate token numbers, which, if attackers steal, they can use the information to compromise an organization. Duo’s two-factor solution is designed with security in mind.
We use asymmetric cryptography, keeping only the public key on our servers and storing private keys on your users’ devices in a tamper-proof secure element. Duo never stores your passwords - meaning your logins stay safe.
We know the most effective security solution is one your users actually use. Our solution only requires your users to carry one device - their smartphone, with the Duo Mobile app installed on it. Logging in via push notification is fast and easy.
We strongly recommend using Duo Push as your second factor, a more secure method than SMS passcodes that can protect against man-in-the-middle (MITM) attacks.
Duo has maintained uptime of greater than 99.99% for more than four years, with a hard service level guarantee backed by SLA. Duo’s servers are hosted across independent PCI DSS, ISO 27001-certified, and SSAE 16-audited service providers with strong physical security.
We provide a high-availability service split across multiple geographic regions, providers and power grids for seamless failover, and our multiple offsite backups of customer data are encrypted.
Duo Security’s operational processes are SOC 2 compliant, as determined by an independent auditor. The SOC 2 report measures internal controls at service organizations relating to security, availability, processing integrity, confidentiality and privacy. The standards are outlined by the American Institute of CPAs (AICPA).
Duo’s two-factor authentication cryptographic algorithms are validated by NIST under FIPS CAVP. Our NIST certifications are available for review for FIPS 186-3 RSA asymmetric cryptography, FIPS 180-4 SHS/SHA hash families and FIPS 198 HMAC algorithm.
A DEA-accredited auditor, Drummond Group, LLC, have confirmed that Duo Push satisfies Electronic Prescription of Controlled Substance (EPCS) requirements for two-factor authentication. Duo can also help healthcare organizations meet strong access recommendations for Health Insurance Portability and Accountability Act (HIPAA).
Duo leverages FIPS 140-2 validated cryptographic algorithms to achieve FIPS 140-2 compliance for Duo Mobile Push and Mobile Passcode, by default with no configuration required.
Duo Push and Passcode authentication methods are built in alignment with NIST SP 800-63-3 Authenticator Assurance Level 2 (AAL2) requirements.

The GDPR replaces the European Union’s decades-old data privacy laws, bringing them more inline with the modern technology landscape. This new law affects any organization that collects and handles EU residents' personal data, regardless of where in the world the organization is located. It governs how these organizations handle and protect personal information (PI) and how they report data breaches. As a provider of secure access solutions, Duo ensures our customers’ data is protected. As such, is committed to GDPR compliance across our organization.
“Using Duo, we have enabled a culture of multi-factor authentication without it being seen as a burden to the user. The experience is pleasant and the protection is unparalleled.”
“The thing that I personally love about Duo is, the interface is absolutely slick. You just can’t beat the fact that it’s one touch, one button, one press.”
