About SentinelSuite

Built by people who
run WordPress sites.

SentinelSuite provides security solutions to diagnose, protect, and monitor WordPress sites — tools we built because we needed them ourselves.

Our mission

Make WordPress
secure by default for every team.

Most security failures we see aren't exotic — they're the basics, missed because the tooling was too complicated. SentinelSuite exists to fix that.

What we believe

Three principles that shape every decision.

01

Clarity beats cleverness

A dashboard a non-engineer can read is worth more than a dozen advanced features no one uses.

02

Defaults must be safe

保護のためにマニュアルを読む必要はありません。安全なデフォルト設定に、必要な人だけが使う高度なオプション。

03

Speak Japanese natively

Documentation, support, and UI — fully bilingual. Not a machine translation afterthought.
