### 2/5 — Defender is not working

*2026-07-22, version 1.1.79080103*

Receiving a “oh something went wrong issue” Dendender will not work until it’s resolved. Please review!

### 3/5 — 好用删不掉

*2026-07-15*

如题

### 4/5 — Me defender

*2026-07-07*

Não permite habitação de VPN no celular iPhone 17e

### 2/5 — Réactivation

*2026-07-06*

Trop souvent désactivé pas normal

### 3/5 — Works, but has Limits & Annoyances

*2026-07-03, version 1.1.78290102*

Microsoft Defender “just works” apparently, but has few details of its findings. Having used this family of defense tools for years on Windows, I expect nothing less—and it seems to deliver!

But the incessant nagging to purchase identity insurance or sign up for Credit Monitoring (even though I already have that through other means) gets old rather quickly! Each new “update” of the app via the App Store causes the user to march through “suggestions” all over again—or put up with the indicator on the app (which may cause the user to miss actual alerts of successful protection from malicious code). Come on, Microsoft, give us an option to decline once & for all the repetitive push to sell identity insurance & protection services!

### 4/5 — ACCOUNTS

*2026-06-26, version 1.1.78020101*

Have not been in my account in a long time . (YEARS) Please help. I have a sixth grade education. Don’t need all the passwords. Don’t even know what to do. Thank you!

### 3/5 — Bug report

*2026-06-24, version 1.1.78020101*

Defender continuously notifies me that my device is not protected. However, it is. I also use Malwarebytes for iOS security. It is on and active. That means my device IS protected. Please address this bug by scanning for other malware apps running and only show the ‘ not protected’ alert if indeed my device is not protected.

### 2/5 — fb comments were tracked by trolls

*2026-06-22, version 1.1.78020101*

the app turns off once I made comments combatting trolls on fb

### 3/5 — No app security

*2026-06-17, version 1.1.78020101*

Once you sign into the app for the first time. There appears to be no security on this app whatsoever.  There’s no four digit code to lock this app. There’s no facial ID to lock and open this app. There’s nothing. So anybody that gets a hold of the iPad can just open the app and see all the information that’s in here. That seems to be a huge flaw for an app. That’s supposed to be there to help you to protect your information. There should be at least a minimum four digit code in a facial recognition ability to open and lock the app.  Every single legitimate app has those abilities. Lord in heaven get with the times.

### 4/5 — None

*2026-06-13, version 1.1.78020101*

Many times, I don’t understand what your security issues are saying about my account. In addition being able to manage such security issues seems too daunting many times. It would be nice if you dumped it down for people like me. Thank you.

### 1/5 — Give me link to solution

*2026-06-11, version 1.1.78020101*

You tell me something’s shut off but you don’t tell me how to fix it.

### 1/5 — States I’m Offline

*2026-08-06, version 1.1.79210103*

Will turn off because it indicates I’m offline. Currently staying I need to connect to the Internet and even though I’m online it won’t work.

### 1/5 — Something went wrong

*2026-08-05, version 1.1.79210103*

Keep getting the something went wrong. Can’t show notifications and history since the update yesterday. Happens on my iPad and iPhone

### 1/5 — 오류수정좀 하세요

*2026-08-05*

앱에 들어가면 상단 알람이 두개 떠있는데 누르면 계속 오류만 뜸..

### 1/5 — Location Privacy concern

*2026-07-10, version 1.1.78290102*

The app claims it can see, “names of Wi-Fi networks (SSIDs) near you and their associated MAC addresses.” If this is true, this app can be used to locate and track any user.

### 1/5 — Wer braucht so etwas...???

*2026-07-07*

Es ist wieder einmal ein Beleg dafür, dass Microsoft bestenfalls alles von allen erfahren will! Systemübergreifend für alle Betriebssysteme greift der Konzern auf Daten zu, die man eben freiwillig preisgibt! 
Mal ehrlich: iOS- und iPadOS-Systeme etc. brauchen so etwas nicht! Und im Windows-System werkelt der Defender ohnehin vor sich hin und macht einen relativ guten Job! Was das hier also soll, erschließt sich mir nicht? Solch eine App hat nicht einmal unsere Rechtsanwaltskanzlei installiert..
Warum auch...?!
Und die sollte doch besonders geschützt sein!!! Aber nicht mit einer App wie dieser!!!

### 1/5 — My hero

*2026-07-03, version 1.1.78290102*

Defender 🤠

### 1/5 — 卡

*2026-06-30*

卡死了！

### 1/5 — VPN always breaks

*2026-06-22, version 1.1.78020101*

More often than not the VPN causes issues. Just now I was unable to even open the app because the VPN stopped working. Then, the app just keeps nagging me to turn it back on and internet stops working again. I love MS but this is border line spam

### 1/5 — What’s the Point

*2026-06-19, version 1.1.78020101*

I am constantly getting “You have 2 unresolved issues…”
Yet when I go to the app, “Everything looks Great!”
There is nothing to resolve. Pick a lane Microsoft. Either there’s a problem or there isn’t. My last issue was 18 months ago, so if I have issues (well, computer ones anyway), show me.

### 1/5 — MS Defender is Frozen

*2026-06-12, version 1.1.78020101*

MS Defender is Frozen and it says that something went wrong after a few minutes. It would be helpful to know why it is frozen.

### 5/5 — Defender of the faith

*2026-08-17, version 1.1.79210103*

We love it!

### 5/5 — Update

*2026-07-29, version 1.1.79080103*

I could not get the dark web thing to work. But I then deleted the app, and reinstalled. For some reason it not works.
It’s proving to be one of the more useful apps. And it has a VPN I think.

### 5/5 — got alert just now

out unable to open alerts keep saying “try again” on my iPhone and ipad

### 5/5 — Defender

### 5/5 — Paul David Jackins MD

*2026-06-27, version 1.1.78020101*

I have worked at Ivy League hospitals from Baltimore, to New York City. A victim of a car accident, seven years ago has damaged my brain. So I appreciate MS Defender helping to protect me from the scammers and identity thieves online out there.

### 5/5 — My defender

*2026-06-09, version 1.1.77280101*

I am happy to have this app that comes with my Microsoft 365 subscription!

### 5/5 — iPhone User
