To find common ground, you need to first conduct meetings together with both teams. This is so that everyone would have the chance to tell each other what are their team's priorities and needs. You need to then set clear rules, guidelines and goals pertaining to the amount of security needed and how to meet the needs of user experience. This is so that they would know what they need to do. You must also make sure that you regularly review the level of satisfaction of your users as well as the level of security. This is so that you would know if it needs to and can be compromised or not.

Align on Goals – Emphasize that security and user experience both aim to protect and empower users. Early Collaboration – Involve both teams from the start to integrate security seamlessly into design. User-Centered Security – Balance protection with usability; security shouldn’t feel like a burden. Threat Modeling Together – Jointly assess risks to develop practical, user-friendly safeguards. Iterative Testing – Conduct usability and security tests to refine solutions. Clear Communication – Foster transparency and understanding between teams. Compromise Smartly – Prioritize risks and adjust security measures where UX impact is too high.

In my humble opinion, it is necessary to explain to each party separately the importance of the other's involvement beforehand to clarify the position, and then bring both teams together to jointly discuss the role and impact of each team on the company and find the root cause of the conflict, and then jointly (very importantly) eliminate this cause.

Finding common ground between security teams and UX designers requires collaboration and a balanced approach: Foster Open Communication: Hold joint discussions to align security needs with user experience goals. Prioritize Risk-Based Security: Implement controls where risk is highest while minimizing user friction. Leverage Adaptive Authentication: Use risk-based MFA to maintain security without unnecessary complexity. Test and Iterate: Conduct usability testing to refine security measures without hindering workflows. Educate Both Sides: Help designers understand security risks and security teams appreciate usability concerns. Aim for Seamless Security: Integrate security into workflows to enhance, not obstruct, the user experience.

Both teams need to stay flexible and aligned with the common goal - whether it's successful delivery, project/product launch, or task implementation. It’s about teamwork, mutual respect, and open communication, with no favoritism. Naturally, security concerns are critical and should never be dismissed without valid reasons. Instead, UX designers must find creative ways to achieve their tasks while adhering to strict security requirements.
