Cisco and Meraki environments sit at the edge of the business, so management exposure, VPNs, identity and software versions matter. The right action starts with the exact platform: Meraki MX/MS/MR, Cisco ISE, Secure Firewall, routers, switches or collaboration infrastructure.
Current watch item
Cisco's September 2026 security advisories included critical and high-severity issues across products such as Identity Services Engine (ISE), Secure Firewall and other enterprise platforms. Cisco ISE CVE-2026-76460 was published with a critical severity rating. Businesses using Cisco infrastructure should compare exact product/version against the current Cisco advisory catalog rather than treating 'Cisco' as one patch domain.
What should you check?
- Inventory Cisco and Meraki devices by product family, model and software/firmware version.
- Review Internet-facing management, VPN and remote-access services.
- Compare product versions against current Cisco Security Advisories and Meraki firmware release notes.
- Verify administrator accounts, MFA/SSO and API integrations.
- Review support/lifecycle status for older appliances and switches.
- Back up configuration and understand HA/failover behavior before upgrades.
What not to do
- Do not assume Meraki cloud management means every appliance is automatically on the required security version.
- Do not expose management interfaces unnecessarily.
- Do not apply an advisory for Cisco ISE, Secure Firewall or another family to unrelated Cisco equipment.
- Do not upgrade a production edge device without validating failover, config backup and business dependencies.
