Key Benefits of ISL Online

- Unlimited Users on All Plans: ISL Online offers an all-inclusive licensing model — you pay per concurrent connection, not per user seat. There are no user caps on any plan tier.
- Custom Branding: ISL Online allows full custom branding, so IT providers and MSPs can present remote sessions under their own company name and logo — a feature not available in RealVNC Connect’s standard plans.
- Managed Private Cloud: ISL Online offers a managed private cloud option for organizations that need to keep data on their own servers. This suits healthcare, finance, and government sectors with strict data requirements.
- Live Chat Support for All Users: ISL Online provides immediate live chat support that is accessible to all users — including trial accounts. This is a strong advantage over tools that restrict support to paying customers only.

1. Remote Access and Control
RealVNC Connect: RealVNC Connect uses virtual network computing (VNC) technology to transmit the remote desktop in real-time — enabling screen sharing and full remote assistance from any location. You install the RealVNC Server on the machine you want to control and use the RealVNC Viewer app to gain access from any device. A direct connection on a local network requires enabling VNC connections on the remote server and opening port 5900 — but the cloud-brokered option skips this entirely.
ISL Online: ISL Online lets technicians tap into client workstations from thousands of miles away through the ISL Light app. For unattended remote computers, the ISL AlwaysOn app provides persistent access even when no end user is present at the remote machine. ISL Online’s client application is just 600KB — significantly lighter than many competitors — which means faster deployment on users’ machines.
⚠️ Warning: RealVNC Connect requires both a server and a viewer app to function. This two-app setup can be confusing for non-technical users who are receiving remote support for the first time.
2. Security and Encryption
RealVNC Connect: RealVNC Connect uses 256-bit AES encryption on every session. It supports multi-factor authentication and treats every connection as though it originated in a hostile environment — safeguarding against unsolicited access. Connecting requires an access password set during the VNC Server installation. An optional Identity Check feature also verifies a catchphrase during the connection process. A connection must be authorized by the server-side device before any session begins.
ISL Online: ISL Online employs AES-256 encryption, two-factor authentication, and granular user access management. Its most notable credential is a 22-year breach-free record — making it one of the strongest options for regulated industries that handle sensitive information. ISL Online also complies with international security standards, which is a key requirement for healthcare and government IT environments.
✅ Test Result: Both tools use AES-256 encryption and two-factor authentication. ISL Online’s 22-year breach-free record gives it a clear edge for organizations in sensitive or regulated sectors.
3. File Transfer
RealVNC Connect: RealVNC recently added a dual-pane file transfer tool that lets you browse the complete file system on both computers simultaneously. You can transfer files directly between local and remote machines without leaving the session. However, it lacks drag-and-drop functionality — a noticeable gap that some users find frustrating compared to other remote access software.
ISL Online: ISL Online allows easy file transfer between connected computers through its built-in file manager. This facilitates document sharing and program installations during a remote session. The file transfer feature is tightly integrated into the session interface, making transferring files fast and intuitive for support teams.
4. On-Demand Support and Session Management
RealVNC Connect: The on demand assist feature (also called On-Demand Assist) lets support teams quickly connect to a customer’s device for a support session without prior installation on the client end. This is useful for ad-hoc remote support. However, this feature is not part of the main plans — it requires a separate trial and is billed at $197.88 per technician per year.
ISL Online: ISL Online is built from the ground up for remote support workflows. Technicians can share session links or a session code with an end user to start a connection in seconds — making it extremely easy for clients to receive support without any technical knowledge. During every remote session, technicians and end users can communicate through a built-in chat session. ISL Online also unlocks advanced features like multi-session streaming, mobile support for client machines and users’ machines, and collaborative troubleshooting where multiple technicians join a single session.
⚠️ Warning: If your support team relies heavily on on-demand assist for client support sessions, factor in the $197.88 per technician annual cost when comparing RealVNC Connect’s total price to ISL Online.
5. Mobile Device Support
RealVNC Connect: The RealVNC Viewer app is available for iOS and Android devices. You can control a remote machine using touch gestures directly on your mobile device. RealVNC’s cross-compatibility lets the VNC Viewer be installed across Windows devices, macOS, Linux, and mobile devices — giving you access to your office computer or home PC from virtually anywhere. This breadth of platform coverage is a genuine advantage for mixed-OS networks.
ISL Online: ISL Online provides full mobile device support for Android and iOS devices. IT teams can provide remote support to users on their phones and tablets — not just desktops. This is particularly useful for support teams managing a mix of mobile and desktop environments across clients.
6. Session Recording and Administration
RealVNC Connect: RealVNC Connect includes a suite of admin tools that provide complete access control across all remote devices. Administrators can manage user permissions and monitor connections from a centralized dashboard. Session recording is available on higher-tier plans.
ISL Online: ISL Online provides powerful administration tools including session recording, detailed audit logs, and granular device permissions management. The administrative mode lets IT professionals view the remote user’s screen across multiple monitors and manage users machines with full administrator rights. These tools give IT professionals full control over who can access which remote devices and under what conditions. G2 reviews frequently highlight these as particularly strong for enterprise IT environments.
7. Custom Branding and OEM Options
RealVNC Connect: RealVNC offers an OEM product for software vendors who want to embed remote control directly into their own applications using the RealVNC SDK. Standard consumer and business plans do not include custom branding. This limits RealVNC Connect’s appeal for MSPs who want to present white-label remote support under their own brand.
ISL Online: ISL Online includes standard customization and full custom branding capabilities. IT providers can apply their own logo, colors, and company name to the client interface. This makes ISL Online a popular choice for MSPs and IT service companies that offer support to clients under their own brand.
8. Pricing & Cost
Let’s compare the full pricing structure side by side.
| Plan Tier | RealVNC Connect | ISL Online |
|---|---|---|
| Free | Lite plan — permanent (5 devices) | 15-day trial only |
| 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 cheaper at every paid tier. The Essentials plan starts at $8.25/month — roughly half the price of ISL Online’s Starter plan. However, pricing scales per device, so costs can grow considerably more expensive as soon as you’re connecting to a dozen or more remote computers.
ISL Online: ISL Online costs more upfront but its concurrent connection model includes unlimited users and unlimited managed devices on all plans. For teams of five or more people sharing a license, the effective per-user cost can be lower than RealVNC Connect’s device-based pricing. Enterprise plans start at approximately $24,000 per year, placing it well above RealVNC Connect’s range.
💡 Test Result: RealVNC Connect is $8.65/month cheaper at entry level. But ISL Online’s unlimited user licensing can deliver better total value for IT teams with multiple technicians sharing one account.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|

🆓 Free Trials and Demos
RealVNC Connect offers a permanent free Lite plan (five devices) plus a 14-day trial of paid features — no credit card needed for either. ISL Online provides a 15-day free trial period covering all essential features. Test both before spending any money.
🛟 Support Options
ISL Online provides immediate live chat support to all users — including those on a trial plan. RealVNC Connect limits faster support access to higher-tier plans. If quick, human-operated support matters to your team, ISL Online wins here.
