Stay private online.
Without the marketing fluff.

Editorial firewall
Vendor relationships never decide what we cover or how we describe it. Disclosures appear next to every recommendation.
Fact-checked
Every guide is reviewed by a second editor against vendor documentation and primary technical sources before publication.
Lawful use only
We help you protect your own privacy and security. We don’t publish guides for circumventing laws, content licences, or workplace policies.
Common questions
Are your guides free?
Yes. Sentrly is supported by ads and our newsletter. All articles are free and require no signup.
Do you accept payment to recommend products?
No. We may earn a commission when readers click through certain links, and that is disclosed clearly. It never affects whether or how a product appears on the site.
Who writes the content?
Named contributors with backgrounds in privacy, network security, and consumer technology. Each article shows the author’s byline and bio.
How often are articles updated?
The “Updated” date on each article shows the most recent fact-check. We aim to revisit popular guides at least every six months.
