A cyberattack rarely stops at the organisation it first enters.
A compromised vendor can become a gateway into a larger enterprise. An attack on a financial institution can affect customers and payment systems. A disruption in the power or telecommunications sector can have consequences far beyond the technology systems that were initially targeted. As India’s economy becomes increasingly digital, cybersecurity has consequently moved from being an IT concern to becoming a matter of business continuity, public safety and national resilience.
This is where public-private collaboration becomes important.
Governments have access to national-level intelligence, regulatory mechanisms and the ability to coordinate across sectors. Private companies, on the other hand, operate much of the technology and infrastructure that keeps the digital economy running. They also see threats first-hand through security operations centres, cloud platforms, network monitoring systems and incident-response teams. Bringing these capabilities together can make the overall response faster and more informed.
From Government Oversight to Shared Cyber Defence
India’s approach to cybersecurity already reflects this idea of shared responsibility.
At the centre of the country’s incident-response framework is the Indian Computer Emergency Response Team (CERT-In), the national agency responsible for coordinating responses to major computer-security incidents. Its role goes well beyond receiving incident reports. CERT-In collects and analyses information about cyber incidents, issues alerts and advisories, coordinates response activities, supports incident handling and publishes guidance on vulnerabilities and security practices. It also works with government departments, public-sector organisations, industry, security vendors, internet service providers, law-enforcement agencies, academia and other stakeholders.
In practical terms, this means that when an organisation encounters a serious cyber incident, the response does not have to remain confined to its own security team. CERT-In can help with the technical process of identifying what happened, containing the damage, removing the underlying cause and restoring affected systems.
That distinction matters. Cyber defence is not simply about building stronger firewalls or buying better security software. It is also about ensuring that information moves quickly enough between the organisations that need it.
Why Information Sharing Matters
Consider a situation in which several companies begin seeing the same malicious campaign. One organisation may identify the phishing email, another may detect the malicious domain, while a third may notice unusual activity associated with the attack.
If each organisation keeps that information within its own security team, others may encounter the same threat without warning. If the information is shared quickly, however, security teams can block indicators, investigate their own networks and strengthen their controls before the attack spreads further.
This is one of the practical purposes of information-sharing mechanisms and sector-based cybersecurity coordination.
India’s cybersecurity framework includes collaboration with Information Sharing and Analysis Centres (ISACs) and sectoral response teams. The idea is relatively straightforward: organisations within a sector can exchange information about threats and vulnerabilities that are particularly relevant to them, while government agencies can contribute wider threat intelligence and coordination.
This model has been recognised in India’s cybersecurity policy approach for several years. Government documents have specifically highlighted ISACs in sectors including banking, telecommunications and power as part of the country’s public-private cybersecurity framework.
Sector-Specific Defence: Why One Model Does Not Fit All
Cybersecurity challenges are not identical across industries.
A banking organisation is concerned with payment systems, customer data and financial fraud. A power utility has to protect operational technology and systems that support electricity generation, transmission and distribution. A telecommunications provider must protect large-scale networks and communications infrastructure.
This is why sector-specific cybersecurity mechanisms are increasingly important.
CERT-In supports the creation and operationalisation of State and Sectoral Computer Security Incident Response Teams (CSIRTs). A sectoral CSIRT
essentially focuses on understanding, preventing and responding to cybersecurity incidents within a particular sector and acts as a bridge between sector stakeholders and the broader national response framework.
The power sector provides a useful example. Dedicated sectoral CERTs have been established for areas including thermal generation, hydropower, transmission, distribution, grid operations and renewable energy. These teams provide a more specialised layer of cybersecurity coordination for infrastructure where a digital incident can potentially have physical and economic consequences.
The financial sector has a similar mechanism. CSIRT-Fin, functioning under CERT-In, focuses on coordinated incident response, information sharing and cybersecurity support for the banking, financial services and insurance ecosystem. In the power sector, CSIRT-Power works on incident coordination, threat intelligence, proactive containment and vulnerability mitigation.
These examples show what public-private partnership looks like beyond a policy document: specialised teams, defined points of contact, information flows and coordinated response mechanisms.
Preparing Before the Attack Happens
One of the biggest mistakes in cybersecurity is treating preparedness as something that begins after an incident.
Effective cyber resilience requires organisations to know beforehand who will make decisions, whom they will contact, which systems are critical, what information needs to be shared and how operations will be restored.
CERT-In’s Cyber Crisis Management Plan (CCMP) is designed around this principle. The framework provides a coordinated approach for identifying, exchanging information about, responding to and recovering from cyber incidents. Sectoral plans can establish senior points of contact, crisis-management committees and 24×7 monitoring arrangements, while organisations are expected to develop their own incident-management plans and participate in cybersecurity drills.
Cyber drills are particularly useful because they expose weaknesses that may not appear during routine security assessments.
India has been using such exercises to test organisational preparedness. According to government data, CERT-In conducted 122 cybersecurity drills and exercises in 2025, involving around 1,570 organisations across government, public and private sectors, including participants from defence, telecommunications, finance, power, oil and gas, transportation, IT/ITeS and state data centres.
The value of such exercises is not simply in testing technology. They test people and processes as well: Who raises the alarm? Who contacts the regulator? How quickly can an affected system be isolated? Can the organisation continue essential services? Does senior management know what decisions it needs to make?
These are the questions that determine how well an organisation performs when a real incident occurs.
Building Skills Alongside Technology
Another area where public-private cooperation can make a measurable difference is cybersecurity talent.
Technology changes quickly, but security teams also need practical experience in handling incidents, investigating attacks and making decisions under pressure. Government agencies, universities, technology companies and enterprises can contribute differently to this effort through training, research, workshops, awareness programmes and technical exercises.
The scale of this effort is significant. Government figures indicate that CERT-In conducted 32 specialised technical training programmes and 95 cybersecurity awareness sessions in 2025, training more than 20,000 officers and cybersecurity professionals across government, public-sector organisations and industry.
This is important because resilience ultimately depends on people. Even the most advanced security platform cannot compensate for unclear responsibilities, inadequate skills or delayed decision-making.
The Difficult Part: Trust
Despite the obvious benefits, collaboration between government and industry is not always straightforward.
Companies may hesitate to share information about an incident because they are concerned about confidentiality, legal exposure or reputational consequences. Organisations may also collect information in different formats or have different thresholds for reporting incidents. Government agencies, meanwhile, need to balance information sharing with national-security and privacy considerations.
Trust therefore becomes as important as technology.
For public-private partnerships to work effectively, organisations need clear rules around what information should be shared, with whom, how it will be protected and
how it can be used. They also need secure channels for communication and clearly defined responsibilities during an incident.
Without these foundations, information-sharing initiatives can remain largely reactive. With them, the same information can become an early-warning mechanism.
The Next Challenge Is Already Taking Shape
The cybersecurity landscape is becoming more complicated as organisations adopt artificial intelligence, cloud services, connected devices and other emerging technologies.
AI, for example, can help security teams analyse large volumes of data and identify unusual activity, but the same technology can also make phishing, impersonation and other forms of cyber-enabled fraud more convincing. Cloud environments and connected devices create additional points that organisations need to secure.
This makes collaboration even more relevant. A government agency may identify a broader campaign, a technology provider may detect a new attack technique, and an enterprise may observe how that technique is being used in a real environment. Bringing these observations together can provide a much clearer understanding of the threat.
The future of cyber defence will therefore depend less on individual organisations trying to build an impenetrable perimeter and more on how effectively the wider ecosystem can detect, communicate, coordinate and recover.
Moving From Partnership to Collective Resilience
Public-private partnership in cyber defence is ultimately about turning separate capabilities into a coordinated system.
Governments cannot monitor every network. Private companies cannot independently assess every national-level threat. Researchers may identify vulnerabilities before either side has seen them in the wild. Sectoral response teams may understand the operational impact of an attack better than a general-purpose security team.
Each brings a different piece of the puzzle.
India’s evolving cybersecurity framework—from CERT-In and sectoral CSIRTs to information-sharing mechanisms, cyber drills, crisis-management plans and industry engagement—shows why collaboration is becoming an essential part of national cyber resilience.
The goal should not simply be to respond faster when the next major cyberattack occurs. It should be to build an ecosystem where threats are identified earlier, intelligence is shared responsibly, organisations know how to respond, and essential services can continue even when systems come under attack.
In a digital economy, resilience cannot belong to one organisation or one sector. It has to be built collectively.
