Let go of Cisco Umbrella SIG and overcome!
A lack of security service edge (SSE) vision
Secure web gateway (SWG) is crucial to security service edge (SSE), but Cisco introduced SWG only recently in 2018. Cisco has made multiple attempts to build a SSE (and SASE) platform, with secure access being their latest effort. However, some components remain poorly integrated.
Integration challenges
Cisco Umbrella SIG lacks native integration across different technology stacks, inevitably leading to performance, security, and resiliency issues. There is also a risk of dependency on Cisco products, making future changes costly.
Usability issues
Cisco Umbrella SIG is not user friendly. Initial deployment hassles and a clunky UX pose significant challenges for security and networking teams.
