1. Remote Access and Management
RealVNC Connect: RealVNC Connect uses the VNC Server and VNC Viewer setup to connect to any remote machine. You install the server on the target device and the viewer on your local device. It supports cloud-brokered connections, which means you don’t need to open firewall ports for most setups.
ISL Online: ISL Online lets technicians connect to client machines through the ISL Light app. It also offers ISL AlwaysOn for unattended remote access — ideal when no one is at the remote device. The client app is only 600KB, which means faster downloads and less friction for end users.
⚠️ Warning: RealVNC Connect requires both the server and viewer app to be installed. This can confuse non-technical users during first-time setup.
2. Security Features
RealVNC Connect: RealVNC Connect uses 256-bit AES encryption on all connections. It supports multi-factor authentication and treats every session as starting from a hostile network. An optional Identity Check feature verifies a catchphrase during connection to prevent imposters.
ISL Online: ISL Online also uses AES-256 encryption along with two-factor authentication. Its biggest security credential is a 22-year breach-free record. It is compliant with international security standards — making it especially suitable for regulated industries like healthcare and finance.
✅ Test Result: Both tools offer strong encryption. ISL Online’s 22-year zero-breach history gives it a slight edge for highly regulated environments.
3. File Transfer
RealVNC Connect: RealVNC Connect recently added a dual-pane file transfer tool. You can browse both machines at once and move files directly. However, it does not support drag-and-drop, which is a noticeable gap compared to some competitors.
ISL Online: ISL Online includes a built-in file manager for easy file sharing during sessions. It supports transferring documents and installing programs on remote machines. The file transfer tool is well-integrated into the session interface.
4. On-Demand Support
RealVNC Connect: RealVNC Connect has an On-Demand Assist feature for quickly connecting to a customer’s device. It is designed for IT support teams helping end users in real time. However, this feature is sold as a separate add-on and is not included in the main subscription plans.
ISL Online: ISL Online is built from the ground up for remote support workflows. Technicians can share a session link or code with a client to start a session instantly. Multiple technicians can join the same session for collaborative troubleshooting.
⚠️ Warning: RealVNC Connect’s On-Demand Assist costs $197.88 per technician per year on top of your main plan. Budget carefully if your team uses it heavily.
5. Mobile Device Access
RealVNC Connect: The RealVNC Viewer app is available on iOS and Android. It lets you control remote desktops using touch gestures directly on your phone or tablet. The cross-compatibility works across all supported operating systems.
ISL Online: ISL Online supports connecting from and to iOS and Android devices. It is compatible with a wide range of mobile environments. Support teams can help users on phones and tablets just as easily as on desktops.
6. Session Recording and Administration
RealVNC Connect: RealVNC Connect includes admin tools that give you complete access control across all devices. You can manage user permissions and monitor connections from a central dashboard. Session recording is available on higher-tier plans.
ISL Online: ISL Online has powerful administration tools built in. It supports session recording, user access management, and detailed audit logs. These features make it easy to track what happened during every remote session.
7. Custom Branding and OEM
RealVNC Connect: RealVNC Connect offers the RealVNC OEM product for vendors who want to embed remote access into their own software. However, standard plans do not include white-label or custom branding options for MSPs.
ISL Online: ISL Online includes custom branding on its plans. You can add your own logo, colors, and company name to the interface. This is a strong selling point for IT service providers and MSPs who support clients under their own brand.
8. Pricing & Cost
Let’s compare the pricing plans side by side.
| Plan Tier | RealVNC Connect | ISL Online |
|---|---|---|
| Free / Trial | Free Lite plan (permanent) | 15-day free trial |
| Entry Paid | $8.25/month (Essentials) | $16.90/month (Starter) |
| Mid-Tier | $16.50/month (Plus) | $34.90/month (Standard) |
| Top Tier | $29.75/month (Premium) | $54.90/month (Premium) |
RealVNC Connect: RealVNC Connect is significantly cheaper at every tier. The Essentials plan at $8.25/month is ideal for individuals and small businesses. However, pricing scales per device — so costs grow as your device count increases.
ISL Online: ISL Online costs more upfront but offers unlimited users and devices on all plans. The concurrent connection model means a small team can share one license efficiently. For large teams, the per-connection pricing can actually work out cheaper than per-device models.
💡 Test Result: RealVNC Connect is $8.65/month cheaper at entry level. But ISL Online’s unlimited user model can deliver better value for teams of 5 or more people.
