Do you need security and Web protection for iOS?
Yes, lookout! If you surf the web, log into email or use public Wifi, you are exposing your privacy and sensitive information (like passwords and browsing history) to online threats.

Your iPhone and iPad carry a lot of information and may be at risk. Norton has an all-new security app which helps deliver powerful protection for your device and personal information against cyber threats and online scams.

Norton Mobile Security notifies you when it’s time to take action. Help stop cybercriminals from stealing your passwords, bank account number or other personal information.

►Wifi Security - Uses advanced scans to help detect and notify you about unsecure Wifi networks, and those under attack by cybercriminals eavesdropping on your Wifi connection to steal or glean personal information from the web sites you visit or infecting your device with malware.

►Web Protection - Helps detect and safeguard you from navigation to scam and malicious websites when using your preferred browser, app, SMS, and Email. Helps keep your device clean from viruses and malware as well as privacy of your personal information secure by helping you avoid online scams.

►Device Security - Alerts you when your operating system (OS) is out of date, so you can take action to secure and protect your device against vulnerabilities that could allow cybercriminals to take control of it or steal your personal information.

Our Wifi Security warnings are:
►Wifi Security Green: No suspicious activity detected.

►Wifi Security Orange: You’re connecting to an unsafe or unsecured network. We recommend using a VPN service like Norton Secure VPN to ensure your data privacy.

►Wifi Security Red: The network you’re connecting to is under a man-in-the-middle attack, where an unknown party on the same network is spying on your online activity. We highly recommend that you disconnect.

Are there email scams for iPhone users? Yes. Your iPhone may fall victim to phishing or virus scams just like any other device. This is where you are asked to click on a link for various reasons and end up providing your personal information (like user names and passwords to your accounts) and inviting this way viruses and malware. This may occur through email or text messages.

Are there risks with an outdated OS? Yes. An outdated OS can create vulnerabilities and opportunities for cybercriminals. By notifying you of the latest security patches and iOS updates, Norton Mobile Security helps you keep your operating system up to date – one of the best ways to stay secure from old vulnerabilities and exploits.

Federal Witness loves the app

I’m a witness in a federal anti- corruption probe and under constant attack from state-level hackers. Some of the complaints in the reviews are clearly man-in-the-middle attacks, so I’m assuming those folks are also of interest to shadowy criminal networks for whatever reason. I find Norton Security to be highly effective in keeping the bad guys out on PC and iPhone. For those with advance security needs, Norton Security is an excellent security product but I learned early on (after much heartache and frustration) that I personally had to reinstall my operating system, take my network offline to restore it to default, create a strong password and enable security tools like firewall, DOS protection, etc., before downloading - using a VPN -and installing any security software. Also, once downloaded, make sure the file you downloaded actually came from the manufacturer. These criminal hackers, many working for private intelligence firms (a la Harvey Weinstein), are experts at creating look alike files that do not really work, as one reviewer described, but infect your machine with keyloggers and all sorts of other crap. I have been unhackable for months now, thanks to these methods and awesome security programs like Norton. If you go offline, start over by reinstalling your OS and securing your network (while not connected to the internet)m, and then run Norton and a VPN on your PC (I used ProtonVPN) you will be much more secure. Good luck.

Did not work for me (sighs)

Unfortunately it did not work for me the way I thought it would, these are the problems I had to endure during the time I used it:

- Battery Drain: My phone is a new iPhone 8S Plus and the amount of battery drained before and after having this app is absurd. I could have my phone without charging under normal circumstances for up to (2) days, before installing the app, and after installing it, I had to charge it at least twice a day. Not good at all.

- Data consumption: Most of the data consumption after installing this app (at least 70%) came from the app itself. I never had to use up to 5 Gb in one month before installing this app and I was very surprised and annoyed that it would be this way. My normal data usage would be up to 2Gb when really busy. Outrageous!

- Internet Connection Issues: Main problem that forced me to uninstall the app was the connectivity issues when I was not connected to my home or work network. I always had to turn off the VPN connection to use the internet when on the road, which cancels out the purpose of the app.

Overall, it works great on my laptop, I love it for its easy-to-use approach on my computer but for my phone it was not the case, unfortunately.

Norton Still Has Serious Problems

Norton, Please fix this app so we are protected & able to use our devices. Having internet security in today’s tech environment is crucial. The problem is I can not use my device unless I sign out then sign back in repeatedly. I currently have the fastest internet service in my area, 1 gbps or 1,000 Mbps. My iPhone can utilize an estimated 350 mbps. That is more than enough for me to surf the internet while I download a movie, download a complete O.S. Etc. The problem is my service acts worse than DSL because of this situation. Norton has tried to fix the problem but every attempt has been a complete failure. Every time I see there’s a new update I cross my fingers hoping they will correct the problem. Instead we are let down. Norton is supposed to be the Standard in internet security. I prefer Norton over other products in the industry. The Norton brand is taking a hit because they cannot perform like they have in the past by correcting problems effectively & efficiently. I know you can fix this problem if you put enough of your top assets on it. At this point you have to do something. I will be happy to edit my review once the situation is handled.
