Castle vs SSLMate: What are the differences?

Developers describe Castle as "Track security events or any unstructured data from your web backend or mobile app, and Castle will look for anomalies". Castle looks for suspicious login patterns without bothering the legitimate user nor the site administrator. The fully-automated anti-hijack engine identifies potential account compromises based on where the user logs in from and how they navigate the site. On the other hand, SSLMate is detailed as "Buy SSL Certificates from the Command Line. Automate your renewals". SSLMate is the easiest way for developers and sysadmins to buy SSL certificates.

Castle and SSLMate can be primarily classified as "Security" tools.

Some of the features offered by Castle are:

• Security Analytics
• Threat Alerts
• Login Notification Emails

On the other hand, SSLMate provides the following key features:

• No complicated openssl commands.
• Certs delivered straight to your server.
• Automatic renewals with cron.
