Remote Access & Network Resilience in Orange County
Your team should reach what they need from anywhere, and a dead firewall or a down internet line should not stop the day. We pick the right access method for each job and keep the network behind it watched.

What Does Secure Remote Access Include?
Secure remote access lets staff reach company files and applications from outside the office without exposing your network. It includes an access method matched to each job (VPN, RemoteApp, or cloud), a monitored firewall, sign-in protection such as multifactor authentication, and a plan for what happens when a device or an internet line fails.
Most of our clients do not need one method for everyone. Your accountant may need a server-based program. Your sales team may only need Microsoft 365. Giving each group the simplest safe path is what keeps remote work free of VPN headaches. For the wider picture, see our remote work IT setup guide.
VPN, RemoteApp, or Cloud: Which Does Your Team Need?
The right answer depends on where the work lives. Here is how we sort it.
VPN
An encrypted tunnel from a laptop to your office network. Best when staff need file servers, printers, or internal systems that live on-site.
RemoteApp
A program runs on a central server and appears on the user's own computer. Best for software that must sit next to its database. The data stays on the server.
Cloud access
Files and apps live in Microsoft 365 and other cloud services, so staff sign in from anywhere with no tunnel at all. Best when little is left on-site.
We have run all three for Orange County clients. For a Seal Beach construction firm, we deployed Fortinet firewalls with secure VPN tunnels so project managers could reach the central server without exposing the network. Read how we secured that firm's infrastructure.
For an Irvine manufacturer, the work was keeping RemoteApp healthy. Two Remote Desktop servers had piled up hundreds of thousands of stale firewall rules, and we cleaned them out and automated the upkeep. See resolving registry bloat and firewall rule issues.
What Happens When Your Office Internet Goes Down?
Here is what is standard, and what we build when you ask.
24/7 firewall monitoring
We watch your firewall around the clock and get alerts when something changes or fails.
High-availability firewall pairs
Where installed, two firewalls work as a team (active-passive). If one fails, the other takes over.
Satellite for remote sites
Field offices and job sites that cannot get a good wired connection can run on satellite internet.
Failover is available on request
Automatic failover to a second internet line or LTE is not included by default. If your business cannot afford to lose its connection, we design it with you and quote it separately. Tell us how long you can be offline and we will work backward from there.
Resilience also means being ready to recover. Pair your network with tested backup and recovery and the 24/7 watch of our managed IT services.
How Do You Keep Remote Sign-Ins Safe When Staff Travel?
We set up approved-country sign-in policies, so a login from a country you do not operate in is blocked, even with a valid password. When someone travels, we handle a temporary exception when you ask.
The rules behind this are covered on our identity and access management page. For proof, see what multifactor authentication did in two real client incidents and how we implemented Zero Trust in Microsoft 365.
Is Your FortiGate VPN Ready for FortiOS 7.6.3?
Starting with FortiOS 7.6.3, Fortinet removed SSL VPN tunnel mode and told customers to move to IPsec VPN. On some smaller models, browser-based SSL VPN is gone too. If your remote staff connect through SSL VPN and your firewall updates itself, they could lose access overnight.
We have moved our Fortinet clients from SSL VPN to IPsec as a standard step. IPsec is an open standard from the IETF, though FortiGate's own implementation is proprietary. Fortinet explains the change in its own technical tip (opens in a new tab).
Not sure which version you run? Take 15 minutes and we will check. Our cybersecurity services cover the firewall as part of the stack.
Remote Access & Network Resilience FAQs
Do we need a VPN for remote work?
Not always. A VPN is the right tool when staff need to reach something inside your office network, like a file server or a line-of-business application. If your files and apps already live in Microsoft 365 or another cloud service, staff can sign in securely without one. We match the access method to the job.
What is RemoteApp?
RemoteApp is a Windows feature that runs an application on a central server and shows it on the user's own computer, as if it were installed there. The data stays on the server. It suits programs that need to sit close to a database, like accounting or manufacturing software.
Can you keep our remote access running if the office internet goes down?
Standard service includes 24/7 firewall monitoring and alerts, high-availability firewall pairs (active-passive) where installed, and satellite internet for remote sites. Automatic failover to a second internet line or LTE is something we design on request. It is not included by default.
What is a high-availability firewall pair?
It is two firewalls set up as a team. One handles traffic (active) while the other waits (passive). If the active unit fails, the passive one takes over, so a dead firewall does not take your office offline. It protects against hardware failure, not against an internet provider outage.
Is Fortinet removing SSL VPN?
Starting with FortiOS 7.6.3, Fortinet removed SSL VPN tunnel mode, and some models lose browser-based SSL VPN too. Fortinet's guidance is to move to IPsec VPN. We have made that move standard across our Fortinet clients, so staff keep connecting after a firmware update.
What is the difference between SSL VPN and IPsec VPN?
Both create an encrypted tunnel from a laptop to your office. IPsec is an open standard published by the IETF, and it is the method Fortinet recommends going forward. SSL VPN tunnel mode is what FortiOS 7.6.3 and later removed. Staff usually see little difference once the switch is made.
How do you handle staff who travel abroad?
We set up approved-country sign-in policies, so sign-ins from countries you do not operate in are blocked. When someone travels, we handle temporary exceptions when you ask. Tell us before the trip and we will adjust the policy.
How do I know if my FortiGate is affected by the FortiOS 7.6.3 change?
Check your firewall's model and firmware version, and whether remote staff connect with SSL VPN. Auto-upgrade can move a firewall to a newer version without a planned change window. A 15-minute call is enough for us to tell you whether you are exposed.
