Good morning. It’s まさきん.

When you work in data and marketing analysis, you naturally become sensitive about how personal information is handled. I started wondering whether my own smartphone was safe, so I tried signing up for Rakuten Mobile’s “Saikyo Hogo (Strongest Protection).”

Overview of the Option

It costs 990 yen per month. If it is your first time applying, the first 3 months are free.

It is built on Norton™ Mobile Security. On top of that, Rakuten Mobile adds its own coverage and support.

What Exactly Does It Protect?

The main features fall into three broad categories.

First, there are the basic mobile security features, like virus protection and warnings about dangerous websites. It also warns you if you are about to connect to a malicious Wi-Fi network.

Second, there is dark web monitoring. It watches for your email address, phone number, credit card number and so on being bought and sold on shady sites. Apparently it can even tell you where your personal information was leaked.

Third, there is credit card fraud coverage and cyber risk coverage. If something does go wrong, a dedicated communication center helps you recover.

There are also other features such as Web Protection, Wi-Fi Security and Device Security. It warns you when you connect to an unsafe Wi-Fi network. If you often use free Wi-Fi at cafes and similar places, this should give you some peace of mind.

How Trustworthy Is Norton?

Norton’s security, which this option is based on, reportedly uses AI to analyze threat data from around the world. It has also repeatedly earned high marks for protection in third-party testing.

It is apparently also a product recommended by the Japan PTA National Council, which I felt makes it an easy choice for kids’ smartphones too.

Things to Keep in Mind

Part of the coverage reportedly only applies from the 4th month if it is your first time applying. Not every feature is available right after you sign up, so that is worth remembering.

Also, the virus detection and app scanning features are only available on Android. iPhone users should factor that in when deciding.

The site also notes that the personal information protection features may not work properly on some devices. I think it is safest to check the supported products on the official website before signing up.

The Bundled “Saikyo Security Pack”

There is also the “Saikyo Security Pack,” which combines this option with Spam Call and SMS Protection by Whoscall. This one also comes with the first 3 months free, apparently.

If you are concerned about security in general, applying for both together may be the more efficient choice.

Who It Suits and Who It Does Not

Summary

“Saikyo Hogo” is an option that bundles not just virus protection but also personal information monitoring and coverage. Since signing up, I worry about leaks a little less often. Not having to sign up for each of these separately, all for 990 yen per month, is also a quietly nice perk.

If you are interested in calling options, check out the 15-Minute (Standard) Unlimited Calls option too.

I recommend checking the official website for the latest pricing and supported devices.
