What Encryption in transit means
TLS is the standard way to encrypt web traffic in transit. It should cover your website, forms, APIs and connections to databases and third-party services. It is a baseline expectation for any site handling personal data.
Why it matters for your website
Every form submission, login and payment travels across networks you do not control. Encryption in transit keeps that data from being read or changed along the way, including on public Wi-Fi. Browsers also warn visitors about sites that do not use HTTPS, which hurts trust.
Example
A tutoring company's signup form sends parent contact details over HTTPS, so someone on the same coffee shop Wi-Fi cannot read them.
Tips
- Serve every page over HTTPS and redirect all HTTP traffic.
- Make sure connections to email, APIs and databases are encrypted too.
- Turn off old protocol versions your host still allows, if possible.
Common mistakes
- Securing the website but sending form results by plain, unencrypted email to a shared inbox.
- Letting an SSL certificate expire, which triggers browser warnings.
Questions about Encryption in transit
What is Encryption in transit?
Protecting data while it moves between systems, such as from a browser to a server, so it cannot be read along the way.
Is HTTPS enough for encryption in transit?
It covers traffic between visitors and your site. Data moving between your site and other systems, like a CRM or database, should also be encrypted.
What is TLS?
TLS is the protocol that encrypts data in transit. HTTPS is regular web traffic sent over a TLS connection.
