Network Security
Control who can access your network and what they can reach — whether they're in the office, at home, or on the road. Coro delivers Zero Trust access, VPN, firewall, and DNS filtering in one unified module.
Zero Trust Access.
Everywhere.
Traditional VPNs give users full network access once connected — a major security risk. Coro's Zero Trust approach grants access only to the specific applications and resources each user needs, based on their identity, device posture, and location.
Blue Cap IT configures your network security policies and manages the rollout to your team — ensuring secure access without disrupting productivity.
-
Zero Trust Network Access
Users only access the specific apps and resources they need — nothing more. Access decisions are based on identity, device health, and context.
-
Secure VPN
Encrypted tunnels for remote workers who need access to on-premise resources. Simple to deploy, easy for employees to use.
-
Cloud Firewall
Control inbound and outbound network traffic with granular policies. Block unauthorized connections and prevent data exfiltration.
-
DNS Filtering
Block access to malicious, phishing, and inappropriate websites at the DNS level — before the connection is even established.
What Coro Network Security Covers
ZTNA (Zero Trust)
Replace broad VPN access with granular, identity-based access to specific applications. Reduce your attack surface dramatically.
Secure Remote Access
Employees connect securely from anywhere — home, hotel, coffee shop — with encrypted tunnels and device posture checks.
DNS & Web Filtering
Block malicious domains, phishing sites, and unwanted content categories. Protect every device on and off the corporate network.
Firewall Policies
Define granular network access rules. Control which applications, ports, and protocols are allowed for each user group.
Location-Based Access
Restrict access based on geographic location. Flag or block logins from unexpected countries or regions.
Network Activity Monitoring
Full visibility into network connections, blocked threats, and user access patterns. Exportable reports for compliance and auditing.
Frequently Asked Questions
Common questions about Coro Network Security from Blue Cap IT — Zero Trust Network Access (ZTNA), secure VPN, cloud firewall, and DNS filtering for businesses across Maryland, DC, Delaware, New Jersey, Pennsylvania, Virginia, North Carolina, and South Carolina.
What is Zero Trust Network Access, and how is it different from a traditional VPN?
Traditional VPN gives a connected user full access to your network — once they're in, they can reach almost everything. If their credentials get stolen or their laptop is compromised, the attacker has the same broad access. Zero Trust Network Access (ZTNA) flips the model: instead of granting network access, you grant access to specific applications and resources based on identity, device health, and context. A salesperson gets the CRM and Microsoft 365; an engineer gets the dev servers and code repos; nobody automatically gets the finance database. Compromised credentials still give an attacker limited access — only to what that user was allowed in the first place.
Do I still need a VPN if I have Coro Network Security?
Sometimes yes, sometimes no. ZTNA replaces VPN for the most common use case — remote employees accessing cloud apps and modern web-based services — and is significantly more secure. Where you still need traditional VPN is for accessing on-premise resources that don't have a public-facing identity provider integration (legacy servers, hardware management interfaces, internal-only databases). Coro Network Security includes secure VPN capability alongside ZTNA, so most clients run both — ZTNA for modern access, VPN as a fallback for the legacy systems that still need it.
How is Coro Network Security different from Meter NaaS or a traditional firewall?
Different layers of the same stack. A firewall (whether on-premise hardware or part of Meter NaaS) controls what traffic enters and leaves your physical network. Coro Network Security adds identity-aware controls on top: who can access which applications, from which devices, in which locations, regardless of whether they're on your network or working remotely. Most clients run both — a firewall at the perimeter for network-level controls, Coro for application-level Zero Trust access. They're complementary, not redundant.
What does DNS filtering actually block, and how is it different from antivirus?
DNS filtering blocks connections at the domain name level — before your device ever actually connects to a server. When a user clicks a phishing link or malware tries to "phone home" to a known command-and-control server, the DNS request to resolve that domain is blocked, so the connection never happens. Antivirus catches malicious files after they've reached your device; DNS filtering prevents the connection that would deliver them in the first place. Coro's DNS filtering blocks malicious, phishing, and inappropriate-content categories across every device — including ones not on your corporate network.
Where is Coro Network Security deployed — on my network, in the cloud, or on devices?
A mix. The ZTNA and DNS filtering pieces run as cloud services with lightweight agents on each protected device — so they follow your users wherever they go (office, home, hotel, coffee shop). The cloud firewall enforces policies at the cloud layer. There's no on-premise appliance to install, no hardware to maintain, and no need to backhaul remote employee traffic through your office network for filtering. Setup is API-based and Blue Cap IT handles the rollout — most deployments are live in a day with no user disruption.
