What are DevOps and DevsecOps approaches for?

Interested to know, how many companies are using DevOps and DevsecOps approaches? What do they need them for? What tasks and problems in the company's IT infrastructure do they solve?

DevOps kind of helps to unify all areas of development in the IT infrastructure, while DevsecOps emphasizes security. In particular, these technologies help unite developers and support, and enable them to work more cohesively and accordingly efficiently. Before DevOps, developers, testers and administrators often worked in isolation, which led to slowdowns, broken processes and a lot of unnoticed bugs, and with its appearance many companies began to work on software products and their updates in a more structured and qualitative way. Well DevsecOps is also a very important technology, if you want to learn more about it, I advise you to use consulting services https://pharosproduction.com/devsecops-consulting.
