What Can I Expect to Achieve with Software Development When Facing Slow Deployment Times

I’ve been working in software development for a while now, and recently, I’ve encountered slow deployment times and some security vulnerabilities in the projects I’m handling. Given these challenges, what can I realistically expect to achieve with my software development efforts? How can I still drive progress and innovation, even with these hurdles? Are there strategies or approaches I can take to improve productivity and security without getting stuck on these issues?
