Whether you want to install a VPN on your iPhone for on-the-go streaming, need cybersecurity protection for your iPhone, or want to find the best app lock for iPad, this is it: the ultimate guide to the best iOS security apps.

This article contains:

    For starters, let's forget about iPhone viruses — iPhones don't get viruses — and focus on real privacy and security needs for your iPhone, like Wi-Fi protection, a photo vault, password locks, data breach alerts, and the dreaded loss or theft of your phone. All while keeping in mind that iPhones are not completely immune to malicious apps and other threats.

    Best anti-theft apps

    If you've ever had your phone lost or stolen, you know that sinking feeling in the pit of your stomach. Just the thought of your entire identity exposed — bank accounts, social media, email, contacts, photos — is enough to send you into panic mode. 

    Mobile security for iPhones means thinking about both cybersecurity and physical security. Hackers can harm you remotely, but a momentary lapse of conscience can turn a would-be do-gooder into a person who keeps your lost iPhone. These anti-theft apps combine well with more general and essential iPhone security tips.

    Find My iPhone

    This well-known app is for both space cadets and those with bad luck. Find My iPhone is a mobile security app that tracks the location of your iPhone if it's lost or stolen. You can remotely lock your device and erase all data and settings if you suspect it's been stolen. If it's lost somewhere in your own home, you can play a sound at full volume to help locate your phone, even if it’s on silent.

    Lookout Mobile Security

    Top security apps like Lookout back up your personal data and can alert you to the specific location your phone was before the battery drained. So if it's within reach, but just out of juice, you can find it. If it's been stolen, you at least have the sense of security that the data is wiped cleaned and personal photos secured.

    Best applock for iPhone

    You can always hide apps on an iPhone or iPad, but it's even better to lock them. Using an applock for your iPad can prevent kids from accessing inappropriate apps, and an applock for iPhone can add extra security to mobile banking and social media apps in the event of a lost or stolen device. These apps are also great for storing photos and videos with a password.

    Duo Mobile

    iOS security apps like Duo Mobile provide an intelligent two-factor authentication process to ensure your data is protected to the maximum. Duo Mobile approaches security from a zero-trust perspective, which uses granular and contextual access policies to limit information exposure. It’s a great applock for corporations with high risk data vulnerabilities.

    This applock by Locker has some stealth features to protect your most precious apps. Just put it in the locker and slam it shut, only to be opened by FaceID. You can hide specific photos and videos inside this app, but you can also keep entire apps locked inside. The cool part: you can change the Locker app icon so it looks like a calculator or calendar app.

    Note Lock

    Note Lock promises to hide your private notes in plain sight. Using the app, you can keep a personal diary on your phone that's safe from intruders using passcode and pattern locks. If an incorrect login attempt is made, the time, date, and a photo of the culprit will be saved. It's a private notes iPhone app that has some nice style elements as well.

    Best iPhone messaging encryption apps

    For those seeking iPhone security apps that keep hackers, internet service providers, and other prying eyes off your personal information, an iPhone messaging encryption app is what you're looking for.

    The best messaging encryption apps like Signal, Wickr Me, and Dust provide end-to-end encryption that ensures the messages you send and receive are only visible to you and one other person. Period. No one else — not governmental agencies, ISPs, nor even the most dangerous and famous hackers known today — can see what you’re talking about. 

    Messaging encryption apps aren't just for whistleblowers, they're for anyone who likes knowing their personal messages are private. It doesn't matter if everything you do is legal, ethical, and by-the-book: privacy is privacy.

    That's why even popular messaging apps like WhatsApp offer end-to-end encryption. But stay vigilant, a change to Whatsapp's privacy policy (or any other app's policy) could leave your messages or data exposed.

    Best antivirus and malware apps

    It’s well-known that iPhones and iPads technically don't get viruses, but are you still wondering what the best free virus protection is for iPhone? The best choice is an app that keeps your Wi-Fi networks secure and offers 24/7 data breach notifications. 

    One of the reasons you own an iPhone is its built-in defenses against viruses and other types of malware. Apple tightly controls the software that can and cannot be loaded onto an iPhone, making iOS significantly less susceptible to external threats. Still, jailbroken iPhones can carry spyware and are vulnerable to malware. You may even need to learn how to remove ransomware from an iPhone.

    Here, we have the best iOS security apps to stop hackers and protect your iPhone in the same way you protect your computer or laptop. Not sure how to protect your computer from viruses? We've got a list of the best free antivirus software too.

    AVG Mobile Security and Photo Vault

    The most critical element of any free iPhone security app is privacy. With viruses and malware not likely to infect an iOS device, your main concern should be password protection, photo vault, and Wi-Fi security. For this, we highly recommend AVG Mobile Security.

    AVG Mobile Security for iOS

    One of the easiest ways for a hacker to breach iPhone privacy is through an unsecured Wi-Fi connection. AVG Mobile Security uses powerful detection technology to make sure every network is safe enough for you to use. Then you can connect to the hotel, cafe, or public Wi-Fi network knowing there's no DNS hijacking or weak router issues. 

    AVG Mobile Security is also the best vault app for iPhone. Use a photo vault to lock away 40 private pictures (unlimited on the Pro version). Plus, the password breach feature will alert you if your email password is ever leaked.


    MobiShield is another great iOS security app. The scanning feature conducts a system check to identify potential privacy breaches. With MobiShield you'll know if your iPhone has been jailbroken or if risky software has been unknowingly installed. MobiShield also offers a security vault to encrypt photos, videos, and other files that even filefinder apps can't access.

    Most secure iPhone password apps

    Smartphones don't leave much room for creativity when it comes to passwords. A short PIN or a crafty finger swipe is all that stands between your data and anyone who gets ahold of your phone. That's why you need to know how to put passwords on iPhone apps

    And if you have a lot of apps you want to protect, you’ll need a password manager. A password manager keeps all your app access codes in one secure place. Each app is protected with a unique password, but you don't lose your mind trying to remember them all.

    Plus, when the best way to create a strong password is to use a combination of uppercase letters, lowercase letters, numbers, and symbols — you really might go mad trying to memorize all your app passwords.


    LastPass promises to be your auto-pilot for all your passwords. It's a great hacker-protection app that has three storage categories including website, form fills, and secure notes. This means when you shop online, LastPass will prefill checkout forms with payment details, all while keeping your passwords and data behind locked doors. The app is also super simple to set up, navigate, and use. 

    While LastPass still offers a free version of their password app, their 2020 acquisition by two investment firms has pushed them to give loyal customers an uncomfortable ultimatum: pay up, or lose access across multiple devices. This means the freemium version is only available on one device type at a time — either mobile or desktop.

    As the name suggests, 1Password simplifies your passwords for a multitude of accounts. Not only does it save an unlimited amount of passwords, 1Password also safely secures credit card details and addresses, making it one of the best password manager apps around. You can use Touch or FaceID when using the app and even mark passwords as favorites. It's one of the best apps to stop hackers from gaining access to sensitive information on your phone.

    Bitwarden is a free and open-source password management app that allows you to store an unlimited number of passwords and sync them across all your devices — you can access your passwords via standalone apps, browser extensions, or their website. The open-source software allows Bitwarden to be inspected for security holes and sketchy activity. You can use Bitwarden to store your passwords in the cloud or locally on your device.
