What is a potential drawback of using certificate pinning?

Using certificate pinning can indeed interfere with SSL inspection, making this the most relevant drawback associated with the practice.

When an application employs certificate pinning, it hardcodes specific certificates or public keys that the application trusts. This design choice is primarily intended to prevent man-in-the-middle (MITM) attacks by ensuring that only the pre-specified certificates can establish a secure connection. However, this reliance on specific certificates presents challenges when SSL inspection is enacted. In scenarios where a third-party solutions provider performs SSL inspection to scan traffic for threats, it may replace the pinned certificates with its own. If the application does not recognize or trust this new certificate due to the pinning in place, the connection will fail. This interference can hinder legitimate security practices and can impact users' ability to access web services, leading to potential downtime or degraded service.

The other options provided describe benefits or advantages rather than drawbacks. Enhancing user experience, ensuring faster connection speeds, and providing constant security updates are generally seen as positive outcomes of various practices within digital transformation and cybersecurity but do not address the specific limitations posed by certificate pinning. Therefore, the potential hindrance posed to SSL inspection stands out as a significant drawback of using certificate pinning.
