A network disruption on an internet leased line can create more than a temporary loss of connectivity. In the first five minutes, cloud applications can disconnect, transactions can fail, monitoring systems can lose visibility, and teams may turn to unsecured backup networks to keep business moving. For enterprises, this means an outage can quickly become both an operational disruption and a security risk. This is where ACT’s Secured Internet Leased Line helps businesses stay connected, protected and operational when connectivity is under pressure. 

The Security Blind Spots Enterprises Need to be Aware of

As connectivity drops, cloud applications disconnect mid-session and security tools lose sight of what is happening on the network. This gap matters more in India today, where enterprises are adopting new technology faster than they are securing it, a pattern observed in Seqrite's India Cyber Threat Report. During a disruption, maintaining visibility across an internet leased line becomes even more critical.

Here is what can typically happen when an internet leased line connection is disrupted:

• Firewalls can fall out of sync. During a network switchover, perimeter defences may not remain aligned with the network they are designed to protect. Without secure failover, this can create gaps in traffic inspection when connectivity is already under pressure. 
• Security teams can lose visibility. Most monitoring tools need a live feed to spot unusual activity. A recent industry study on Indian enterprise networks shows 62% of threat detections across Indian networks happen in the cloud, and disruptions only widen that blind spot. ACT's built-in monitoring is designed to keep it closed regardless.
• Devices quietly fall out of policy. A laptop that was fully compliant on the office network can lose that protection the moment it reconnects somewhere else.
• Employees may turn to unsecured connectivity. When the network goes down, staff may switch to mobile hotspots or open Wi-Fi just to keep working, without realising the security trade-off. EY India's research with the ACFE Mumbai chapter found ransomware and social engineering attempts rose 53% alongside unsecured Wi-Fi use in hybrid setups. With resilient and secured connectivity in place, ACT's Secured ILL reduces the need to rely on these unmanaged workarounds. 
• Backup access can become a weak point. When the primary internet leased line fails, businesses rely on guest networks and failover connections to keep operations moving. If these backup paths do not have the same security controls as the primary connection, the fallback itself can become a vulnerability. With ACT’s Secured ILL, the failover path stays protected from the start, rather than becoming a security gap when things go wrong.

For enterprises, the risk only grows with scale. Cloud misconfigurations, exposed APIs and excessive access permissions remain significant weaknesses in India's threat landscape. A sudden network disruption can amplify these existing vulnerabilities by reducing visibility and pushing teams towards alternative connectivity. This is why ACT Enterprise builds security into the connection itself, helping enterprises maintain both connectivity and protection when the network is under pressure. 

How ACT’s Secured Interet Leased Line Changes the Outcome 

A dedicated leased line connection provides the consistent connectivity enterprises need, while ACT’s Secured ILL brings connectivity resilience and integrated security together. This helps enterprises maintain business continuity while reducing the security gaps that can emerge when the primary connection is disrupted. 

• Security controls extend to backup and failover paths, keeping fallback connections protected, preventing unmanaged weak points, outages, and ensuring policy consistency.
• Continuous monitoring supports network visibility during connectivity fluctuations, helping IT teams track anomalies when primary links degrade, improving response speed.
• Dedicated bandwidth maintains reliable business connectivity, ensuring critical applications run smoothly and reducing employees switching to insecure public or personal networks.
• Centralised visibility helps IT teams manage network health, providing a unified view of performance threats, reducing fragmented troubleshooting and improving response efficiency.

For enterprises, the impact of a network disruption is not limited to downtime. It can affect productivity, transactions, customer-facing services and security visibility at the same time. A resilient leased line connection therefore needs to protect the business not only when connectivity is stable, but also when it is under pressure. 

The first five minutes after a disruption can set the course for what follows. With ACT’s Secured ILL, enterprises can build resilience into their connectivity while keeping security part of the equation, so a network disruption does not become a security gap.
