The blind spots in business continuity

Business continuity planning has fundamentally shifted from merely ensuring internal operations to mapping out external vulnerabilities. Modern organizations depend heavily on complex networks of third-party suppliers, software providers, and outsourced partners. According to a recent survey by DRI International, a significant 55% of resilience professionals identified outside vendors and supply chains as their biggest blind spot. This highlights that third-party dependency is no longer just an administrative issue but a core operational risk. Disruptions like extreme weather, cyber attacks, and technology outages frequently expose how vulnerable digital supply chains actually are. Meanwhile, 25% of respondents pointed to legacy IT systems as their primary concern. Old hardware and software are often difficult to maintain, susceptible to cyber threats, and lack the speed required for modern recovery targets. While less visible, executive succession planning also remains a quiet continuity risk. Only 14% of professionals flagged it, yet many organizations still lack clear plans for leadership continuity during a crisis. Lastly, remote work is now largely considered business as usual rather than a major blind spot. Ultimately, organizations must move beyond static supplier lists and internal recovery plans to deeply understand and protect the interconnected ecosystems they rely on daily.

Stop playing with the CISO role. Fix cybersecurity leadership

Organizations expect too much from their Chief Information Security Officers, asking them to handle complex technology while also acting as strategic business partners. This creates a structural flaw because the CISO holds accountability for cybersecurity but lacks the authority to influence broader business decisions across the company. Instead of forcing technical experts to become universal executives, companies should establish a distinct, elevated role: the Chief Security Officer. This position should sit above traditional cybersecurity and focus entirely on protecting the organization's ability to operate and compete. The CSO acts as a senior business leader with the mandate to unite conflicting departments, from legal and finance to technology and operations, ensuring that protective strategies align with business goals. Under this model, the CISO can return to their natural area of expertise. They report to the CSO and focus completely on the technical execution of security, managing architecture, engineering, and operations. This clear division of labor solves the long-standing problem of misaligned security efforts. By separating technical delivery from enterprise-level governance, businesses build a healthier management structure. Security stops being an isolated technology issue and naturally becomes a core part of how the company operates, makes decisions, and protects its future.

Risk Has No Department: Building an Enterprise-Wide Risk Ownership Culture Through ESRM

The traditional model where the security department solely owns all organizational risk is no longer sustainable. Today’s business environment is deeply interconnected, with risks spanning physical security, cybersecurity, human capital, and supply chains. As a result, Enterprise Security Risk Management (ESRM) shifts this paradigm by distributing risk ownership to the actual asset owners—the individuals who create, manage, or benefit from the assets. Instead of making all the final decisions, security professionals now act as trusted advisors who facilitate informed choices, while leaders in departments like human resources, operations, and information technology maintain ultimate accountability. To make this transition successful, organizations must establish a formal risk ownership matrix that clearly maps specific risks to their corresponding functions. This eliminates ambiguity and ensures that risk management is integrated directly into daily operational decisions rather than treated as an afterthought. Furthermore, to cement this culture of shared accountability, organizations should tie risk management effectiveness to leadership performance through key performance indicators and formal risk acceptance thresholds. Ultimately, creating an enterprise-wide risk ownership culture requires strong top-down support from executive leadership and boards of directors, ensuring that risk becomes a strategic business consideration rather than just a compliance checkbox.

How to keep your mission-critical cloud workloads running

To ensure that mission-critical cloud workloads stay online, organizations must take proactive control of their infrastructure's resilience. While cloud providers guarantee the availability of their own hardware, the responsibility for keeping specific applications running falls squarely on the user. True application resilience relies on four essential components: clustering, data replication, failover, and disaster recovery. Historically, clustering depended on expensive physical hardware, but modern software-based clusters offer the flexibility needed for hybrid and multi-cloud environments. These modern setups eliminate single points of failure by seamlessly connecting multiple systems together across varied locations. Meanwhile, keeping data consistently synchronized across these nodes through real-time replication ensures that backup systems are always fully prepared to take over. When a disruption occurs, automated failover mechanisms instantly shift workloads to standby resources without requiring manual intervention or new database builds. Furthermore, a strong disaster recovery plan incorporates geographic distance and asynchronous replication to protect against large-scale regional outages. Using these software-driven strategies not only protects against unexpected crashes but also makes planned maintenance and security patching much safer. By embracing this comprehensive approach, businesses can confidently protect their operations, prevent costly downtime, and keep their most important applications running smoothly regardless of unexpected external failures.

Who gets to decide? The CIO and the new architecture of enterprise authority

As artificial intelligence evolves from merely recommending actions to independently executing them, organizations face a critical new challenge. The core issue is no longer just what the technology can do, but who, or what, has the authority to do it. This creates an enterprise authority gap, where intelligent systems act faster than businesses can define or control their boundaries. Because modern AI interprets intent rather than just following rigid rules, it can easily cross organizational boundaries and create unintended risks if decision rights remain ambiguous. To safely manage this shift, Chief Information Officers must lead the creation of a new enterprise authority architecture. This approach requires businesses to clearly define the desired decision before selecting the technology and firmly separate a system's capability from its actual authority. Furthermore, this delegated authority must be technically enforceable through clear limits, approval gates, and continuous monitoring. Leaders also need to evaluate the true economic cost of autonomous decisions, accounting for oversight, error correction, and potential harm. Ultimately, the new mandate for technology leaders is not about maximizing how much artificial intelligence is deployed. Instead, success depends on how wisely and safely the enterprise distributes decision-making authority to these intelligent systems.

Large Enterprises Targeted in Fake Merger & Acquisition Scams

Cybercriminals are using highly sophisticated social engineering tactics to steal massive sums of money from large enterprises through fake merger and acquisition (M&A) schemes. In a recently uncovered campaign dubbed "Phantom Deal," attackers thoroughly researched mid-level employees who might be involved in corporate dealmaking. The scammers then impersonated company executives and external auditors, crafting a plausible but fake acquisition narrative based on real corporate history. To keep the target isolated, the attackers issued fake non-disclosure agreements and insisted all communication remain strictly on personal channels like WhatsApp, keeping the interactions hidden from corporate security monitors. The ultimate goal was to trick the employee into authorizing a massive wire transfer to overseas accounts. Security experts note that these scammers gather extensive, publicly available details—such as job roles and company history—to make their ruses remarkably convincing. However, organizations can protect themselves by emphasizing strict adherence to internal verification and payment controls. Employees should be trained to question whether the requested process is legitimate, rather than just trusting the identity presented on a screen. When something feels off, the safest action is to immediately halt the process and report the suspicious request through official channels.

Enterprise architecture and software architecture as the core CTO model

Enterprise architecture and software architecture are not just documentation tasks; they are essential frameworks that allow technology leaders to manage change safely and efficiently. Enterprise architecture maps business capabilities directly to applications, data, and risks, acting as the clear rulebook for technological decisions. Meanwhile, software architecture translates those rules into constraints that development teams can actually code against, ensuring systems perform well under stress and failure. Relying on one without the other leads to immediate problems. Enterprise architecture alone becomes an ignored catalog, while software architecture alone creates disorganized local successes that fail to serve the broader business. To succeed, leaders must adopt a continuous loop of deciding, designing, delivering, and defending their architecture choices. While artificial intelligence speeds up development, it also increases the risk of deploying bad systems quickly, making strong architectural guardrails more critical than ever. Effective leaders treat architecture like a living product rather than a static diagram. They build this practice systematically, starting with a thirty-day inventory of vital systems, followed by a ninety-day framework of automated policies, and finally establishing long-term guiding principles. Ultimately, practical architecture directly improves the four outcomes that matter most to any business: delivery speed, operational costs, system risk, and developer retention.

From IT Security to Business Strategy: Navigating Cyber Risk in Digital India

As India rapidly expands its digital economy, managing cyber risk has fundamentally shifted from a narrow technical concern into a core business strategy. For many years, organizations treated cybersecurity merely as an IT function focused on defending perimeters and protecting data. However, the modern digital landscape, fueled by cloud adoption, artificial intelligence, and complex regulatory changes like the DPDP Act, demands a far more holistic approach. Today, business leaders must carefully balance rapid technological innovation with strong governance, compliance, and resilience to maintain stakeholder trust. Cybersecurity is no longer just about preventing unauthorized access; it is about ensuring that critical operations remain consistently available and that users feel psychologically safe when interacting with digital services. Building this digital trust requires enterprises to integrate risk management across their entire ecosystem, including third party vendor networks and evolving AI models. By shifting their perspective, executives can transform security from a defensive cost center into a strategic enabler of sustainable growth. This proactive mindset allows companies to navigate evolving regulatory obligations effectively while adapting their infrastructure to meet user needs at lightning speed. Ultimately, treating cyber risk as a central business priority ensures that organizations can innovate responsibly and thrive securely in India’s dynamic digital future.

Why cyber resilience fails: 5 obstacles holding orgs back

While most organizations want to achieve strong cyber resilience to withstand attacks and keep operations running, the reality often falls short of their goals. Even when leadership provides adequate support and resources, resilience efforts frequently break down in the space between broad strategy and daily execution. Several major obstacles consistently hold companies back from properly securing their systems. Chief among these are mounting technical debt, persistent shortages in skilled security professionals, and increasingly complex identity risks. When older systems are neglected or vulnerabilities go unreviewed, they quietly compound into technical debt. This creates dangerous operational blind spots that attackers can easily exploit. Furthermore, without enough trained staff to manage these environments, security teams struggle to keep pace with evolving threats. The rapid expansion of user identities across different platforms only adds to the challenge, making it difficult to control who has access to sensitive information. Ultimately, true resilience is not just an idealistic goal or a passing project. It requires bridging the gap between management intentions and actual daily operations. To succeed, businesses must actively address these practical challenges, paying down their technical debt and heavily investing in their workforce to ensure that protective measures are flawlessly integrated into everyday tasks.

The next cyber crisis is already taking shape

The financial sector is currently facing an emerging cybersecurity crisis driven by the convergence of two major technological shifts. First, rapid advances in artificial intelligence are drastically lowering the barriers to entry for threat actors. Cybercriminals can now use sophisticated AI tools to quickly identify hidden vulnerabilities, develop exploits, and launch attacks at an unprecedented scale, making threats faster and harder to predict. Second, banks are undergoing a massive, complex transition to post-quantum cryptography to protect their infrastructure against future computing power that could easily break current encryption standards. Because modern banking relies entirely on deeply embedded cryptographic systems, updating them requires years of careful planning. Unlike the Y2K bug, this transition lacks a strict universal deadline, which can dangerously lead to delayed action and increased exposure for institutions. Together, these dual challenges mean that traditional security playbooks are no longer sufficient. Simply recovering systems after a breach is inadequate when facing AI-accelerated attacks and disruptive infrastructure overhauls. Instead, organizations must embrace a strategy of managed degradation. True enterprise resilience now requires maintaining core financial operations and preserving customer trust even while systems are actively compromised. Financial institutions must proactively address this growing imbalance and begin their extensive security upgrades before time runs out.
