Built around real security moments

See where you stand — then fix it

Three signature tools do the heavy lifting: understand your posture, see what apps can reach, and seal what’s private. Each one is deterministic and explainable.

How it works

Three steps, then it stays out of your way

No dashboards to babysit. Set it up once, act on what matters, and let NexGuard keep watch quietly.

1

Scan your device

NexGuard reads the signals your phone already exposes — lock, encryption, updates, app permissions — with your permission and nothing hidden.

2

See your score & fixes

A deterministic engine turns those signals into one score and a short, ranked list of fixes. The AI explains each one in plain words.

3

Lock down what matters

Tighten permissions, move private files into the vault, turn on two-factor — then re-scan and watch the number climb.

6287
A few minutes of fixes moves the needle.Re-scan any time — your score reflects the exact state of your device today.

Built on principle

Security you can actually trust

Three commitments sit behind every single feature — no exceptions, no fine print.

Our promise

Honest by design

We describe only what NexGuard actually does — and build so we can’t betray your trust even if asked.

AI explains, never decides

Scores and verdicts come from fixed rules engines you can reason about. The assistant only puts them in plain words — it can’t invent a number.

Encrypted on your device

Everything is encrypted on your phone before it is sent. Your passwords use a key that never leaves it — we can’t read those, and can’t hand over what we never hold. Photos and documents can optionally use a key we hold, so you can open them on the web — and upload them there, which means we encrypt those ourselves rather than your phone doing it.

No hidden monitoring

Nothing runs silent surveillance. Scam and link checks happen only on content you paste in yourself, when you ask.

Questions, answered

Everything you might want to know

Straight answers on the product, the free plan, billing, security and eligibility.

Is the free plan actually free?
Yes — no card, no trial countdown, no expiry. Paid plans raise daily limits and vault storage; the free tier stays free.
Is this an antivirus?
No. NexGuard works on configuration and exposure — weak locks, stale patches, over-permissioned apps, risky settings — rather than malware signatures. See what it does.
Can you read what’s in my vault?
Your passwords and authenticator secrets, no — those use a key that cannot leave your phone. Photos and documents you choose to open on the web use a key we hold, and we say so plainly rather than pretending otherwise. Which is which.
Does it watch me in the background?
No. There is no access to your messages, calls, contacts, microphone, camera or screen. Scam and link checks run only on text you paste in yourself.
Which devices does it run on?
Android 8.0 and newer, no root required. Full compatibility details.
Where does the AI fit in?
It explains findings in plain language. It never produces the score or the verdict — those come from deterministic engines every time.
