Code Signing Certificates

Protect Your Software with Code Signing Certificates from the World’s Most Trusted CAs

Code signing certificates help show end-users that your software/apps/drivers are safe to download and install. As you might imagine, this helps improve your install rates, brand reputation, and partnerships. Code signing certificates do this by enabling you to authenticate yourself or your organization with trusted certificate authorities (CAs).

By digitally signing your executable files with your code signing certificate, users will know that the software they’re installing actually came from you AND that the file has not been tampered with. In addition, your users won’t see “unknown publisher” warning messages when they’re downloading or installing your software.

Standard Code Signing vs EV Code Signing

Purchasing and signing your software with a standard code signing certificate is sure to improve security, trust, download rates, and brand reputation. However, there is a more powerful upgrade available – extended validation (EV) code signing certificates.

Let’s compare the two:

EV Code Signing Certificate Benefits

With an EV code signing certificate, you get two major advantages.

1. Build trust with Microsoft SmartScreen® Application Reputation filter – This pesky filter can cause a lot of headaches for software publishers. You can eliminate SmartScreen warning messages with an EV code signing certificate while the OV code signing certificate will take longer to build trust.

2. Better protection – EV code signing certificates use two-factor authentication (password and encrypted USB token). This offers better security over your private key and in turn, for your business and users.

3. More Control – You can install your EV Code Signing Certificate on an HSM, which allows you to have the control to choose which employees have the ability to sign code with it.

Standard Code Signing Certificate Benefits

With a standard code signing certificate, you get a few advantages as well:

1. More Affordable – If you feel that a standard code signing certificate is a better choice for you, then you can have peace of mind knowing that you are saving money on your purchase.

2. More Flexible – You can get a standard code signing certificate as organization validated (OV) or individual validated (IV). This means the option is available for both an organization or for individual software developers, which the EV does not offer.

3. Still Effective – Yes, you are saving money, but you are not getting an inadequate product. A standard code signing certificate will still reduce warning messages, build trust with users and continue to build more trust and build up your brand reputation over time.

Benefits of Using a Code Signing Certificate

Injecting malware, adware, or other nefarious code into legitimate software is a favorite tactic of many hackers. Code signing helps you avoid this type of attack. That’s right—think of your digital signature as a digital seal and if that seal is broken, you know something is wrong!

Reason 3: You will be ahead of the game with potential partnerships.

Many companies require publishers to have a code signing certificate before doing business with them. Show up prepared with a code signing certificate from a top CA!
