I think Cisco has the highest marketshare in terms of commercial routers, and probably a higher percentage of use in areas that might be of state actor interest. If you have a WatchGuard for example there may be the same amount of vulnerabilities but less incentive to find them, and less people looking for breaches after the fact.
