The Challenge

The three essential challenges
facing the smartphone.

Communication paths, credentials, and organizational rollout——
three challenges that smartphones face today.

Theme 01

Trust in the communication path

Risks from suspicious Wi-Fi environments, captive portals, and DNS hijacking continue to grow.

It checks DNS responses, certificates, exit IPs, and Wi-Fi state together, and warns of suspicious signs.

Theme 02

Protecting credentials

Password leaks, phishing, and card theft grow ever more sophisticated.

With passkeys (FIDO2 / WebAuthn), private keys are never sent to Nayutal servers and are held in the OS protected store.

Theme 03

Scalability of organizational rollout

Piecemeal measures hit their limits; a way to deploy across the whole organization at once is needed.

Standalone app distribution comes standard; SDK embedding is also available subject to verification.

Why Nayutal Guard

The technical approach
behind Nayutal Guard

How Nayutal Guard responds to each of the three challenges

01

DNS response verification

Cross-checks DNS responses for target domains to detect signs of tampering.

Catching what a single DNS check cannot, it verifiespath consistencyas well.

02

Certificate checks for key services × risk scoring

It integrates DNS, certificates, exit IPs, and Wi-Fi to rate risk on four levels, from Safe to Critical.

Combinations that look normal in isolation are caught bysimultaneous evaluation of multiple signals.
