ACT Secured ILL: How India's Most-Targeted Enterprises Can Stop Cyber Threats at the Gateway

 

For digital enterprises in India, an Internet Leased Line (ILL) is the gateway for all mission-critical traffic. When that gateway is not adequately guarded, the entire enterprise network becomes vulnerable.

The magnitude of the threat is staggering. In 2025, India recorded 265.52 million cyber threat detections across more than 8 million endpoints - averaging 505 detections every minute. High-impact IT outages cost a median of $2 million per hour, with 39% of enterprises experiencing such outages weekly.

Today, the ambition of just being online is not enough. From an enterprise security standpoint, an unsecured connection is the digital equivalent of leaving the front door open in a high-crime neighbourhood. The consequences range from immediate IT costs, productivity loss to reputational and legal damages.

To counter this, enterprises must embrace embedded security. By considering it as fundamental infrastructure, their IT teams will be better placed to tackle the surging cyber aggression. ACT Enterprise enables this readiness through a Secured Internet Leased Line (ILL) solution.

 

What ACT Secured ILL Delivers

 

ACT Secured Internet Leased Line bundles dedicated symmetrical bandwidth with a fully managed enterprise firewall. By moving protection to the perimeter of your network, you stop threats before they enter your local environment. Key features include:

• Firewall as first line of defence: Blocks Trojans, viruses and ransomware before they reach internal systems. Actively updated and patched by security professionals.
• Real-time traffic monitoring: Enabled by AI capabilities integrated at the device level, provides real-time analyses with detection of suspicious behaviour allowing for timely responses.
• URL filtering: Blocks malicious, unsafe or non-business websites, reducing phishing and drive-by download risks.

 

Enterprise benefits at a glance:

 

• Lower total cost of ownership compared to in-house deployment, with no upfront capital expenditure on firewall hard
• ware.
• Reduced downtime costs through proactive 24/7 monitoring by ACT's Network Operations Centre.
• Ease of connectivity management with a single provider for both bandwidth and security.
• Predictable operational expense model that simplifies budgeting.

 

The Vertical Threat Landscape - A Tailored Approach

 

A "one-size-fits-all" approach fails when critical systems are targeted. ACT Enterprise offers a managed model where you define the risk tolerance, and we deliver the outcomes: policy hygiene, real-time monitoring, and audit-ready logs.

Below are three vertical-specific analyses highlighting the urgency of embedded network security.

 

1. Higher Education: Securing the knowledge vault

 

Universities manage vast amounts of intellectual property and personal data, often across open campus networks.

The Landscape: India's education sector remains the primary target for cyberattacks globally. Institutions face an average of 7,684 weekly attacks per enterprise that is more than double the national average of 3,195 attacks.

The Risk Factor: Education networks are extremely difficult to watch and control. With hundreds of students connecting personal devices to open campus Wi-Fi, the attack surface is massive.

The Impact of Downtime: From derailing exam procedures to enrolment and other admin processes and fee payments, and systems holding proprietary research, any downtime can prove disruptive and harm credibility and long-standing relationships.

Under the DPDP Act, educators are now legally responsible for student data. A single breach triggers heavy financial penalties and legal scrutiny.

The Secured ILL Advantage: The university can implement automated threat blocking and content filtering for malware, viruses, unauthorised access and zero-day threats proactively. This ensures detection and prevention right at the gateway.

Application blocking and URL filtering of malicious content deter users from accessing potential dangerous websites and unauthorised apps. Malware stops at the perimeter before it ever touches a student's personal device or the university's internal research servers.

 

2. BFSI (Banking, Financial Services, and Insurance) - Defending the Digital Ledger

 

In the high-stakes BFSI industry, security plays a vital role in preserving liquid assets, customer data and public trust.

• The Landscape: The BFSI sector accounts for 84% of global phishing activity. In India, the incidence of payment fraud rose tenfold to 2.8 million between 2021 and 2025.

The Impact: Losses have jumped nearly 40 times, reaching ₹23,000 crore.

The Risk Factor: For a bank, a compromised connection is an invitation for credential theft. Once an attacker gains a foothold, they can bypass traditional security layers to initiate unauthorised transfers or hold critical databases to ransom.

The Secured ILL Advantage: In the BFSI context, this includes encrypted traffic inspection and API-level threat blocking without slowing transaction processing. Encrypted SSL traffic can hide threats that bypass traditional security tools. Our solution includes an SSL inspection capability that detects and blocks these concealed threats.

Secured connectivity provides real-time threat inspection and enhanced protection from advanced exploits like Distributed Denial of Service (DDoS). Banks for example, gain timely visibility and can scrutinize every packet entering their network for malicious intent, fulfilling both regulatory compliance and the business necessity of protecting customer wealth.

 

3. Healthcare - Fortifying Healthcare Networks

 

Being a modern healthcare provider today means investing in telemedicine, cloud-based Electronic Health Records (EHRs), and connected medical devices. All this digital transformation means a wider attack surface.

The Landscape: India's healthcare sector has emerged as the prime target for global cyber threats, and endured more than 8,600 cyberattacks per organisation each week, at four times the global average. The average breach costs around ₹4.2 crore and takes 197 days to detect.

The Risk Factors and Downtime Impact: For healthcare providers, a network breach is beyond minor operational friction, causing:

• Irretrievable Data Loss: Unlike credit card details that can be cancelled, patient medical records are permanent, unchangeable, and highly lucrative on the dark web.
• Operational Disruption: Network downtime halts critical systems like diagnostic imaging, digital prescriptions and emergency room coordination.
• Patient Safety Risks: In healthcare, seconds save lives. Downtime or data manipulation directly compromises patient care, surgical schedules and emergency response capabilities.

The Secured ILL Advantage: ACT Secured ILL slashes the 197-day detection window to real-time alerts. High-uptime SLAs ensure that life-saving IoT systems remain online, while network-level safeguarding ensures compliance with stringent data protection laws, which improves patient trust.

 

Future Readiness Through Managed Security

 

With India's cybersecurity spending projected to reach $3.4 billion in 2026, an 11.7% increase from 2025, enterprises are allocating more budget to proactive defences.

ACT Secured ILL shifts focus from buying hardware to buying a resilient, consistently managed connectivity service. Built on high-speed fibre and supported by proactive threat detection at the gateway, it delivers the digital backbone for India's most critical sectors. Where trust, continuity and reputation are vital, it allows these enterprises to focus on core business, not network-related troubleshooting.
