Maintain Cybersecurity Continuity During Organizational Shifts

Learn how organizational changes — whether leadership transitions and restructuring or mergers and digital transformation — create unique cybersecurity vulnerabilities that threat actors can exploit.

In brief:

• Organizational changes can disrupt cybersecurity continuity. Leadership transitions, merger and acquisition (M&A) deals, restructuring, and digital transformation projects open security gaps that attackers actively exploit.
• Build a formal continuity plan before you need it.
• Include information technology (IT) and security teams in planning from day one of any major change, with cybersecurity checkpoints built into project timelines rather than bolted on later.
• With 60 percent of breaches caused by insiders, mass layoffs and restructuring create dangerous access control gaps when former employees retain system access.
• Run tabletop simulations specific to your changes and conduct pre- and post-access audits to catch vulnerabilities before they become breaches.

Whether it’s a merger or acquisition (M&A), a leadership transition, or digital transformation, major organizational shifts create unique cybersecurity vulnerabilities. If cybersecurity isn’t part of the plan, delayed software updates, forgotten controls, shadow IT, and unknown access points mean open season for attackers — even if these windows are open for only a few minutes.

Organizational milestones are exciting and inspiring, and they shouldn’t come with a $4.8 million price tag resulting from a preventable data breach. In this article, we’ll discuss what disrupts cybersecurity continuity the most, how to build an actionable continuity plan, and real-world tactics to maintain security through major changes.

What Disrupts Cybersecurity Continuity Most

Modern-day cybersecurity encompasses more than advanced firewalls, network segmentation, multifactor authentication (MFA), and security awareness training — it’s not just an IT responsibility.

It’s a living, dynamic process that should be continued through constant change and affects the entire organization — from top executives to third-party partners. However, many organizations falter during moments of major disruption, whether it’s leadership shake-ups or budget realignments.

Here are some changes that commonly disrupt cybersecurity continuity:

Leadership or Ownership Changes

New executive leaders may introduce new initiatives, priorities and budget shifts. Additionally, leadership turnover can result in significant talent gaps within IT or security departments.

For example, a sudden shift to a cloud-first strategy from a new chief product officer might delay a critical on-premises security upgrade if engineering resources and funding are reallocated. This could quickly leave outdated legacy systems exposed and unsupported.

Mergers, Acquisitions or Divestitures

Research shows a 400 percent increase in phishing attempts on acquired companies after M&A deal announcements. Cybercriminals are lying in wait to exploit any vulnerabilities or gaps that may exist. Each entity in an M&A transaction may have its own systems, resulting in duplicate data without proper oversight.

Perhaps both organizations require different levels of authentication, and all employees will need to migrate to one policy or another. Merging teams might create shadow IT and dubious access controls, adding more prime windows of opportunity for cybercriminals to attack.

Organizational Restructuring or Layoffs

Insider threats are responsible for 60 percent of data breaches. A major company layoff or restructuring, which offboards hundreds or thousands of employees at one time, may create significant gaps in access controls.

Perhaps accounts are left open, and disgruntled former employees still have access to sensitive files, documents and software. The insider threat risk quickly becomes real if security processes are overwhelmed and access isn’t revoked.

Digital Transformation Projects

Digital transformation promises agility, cost savings, and a strong competitive edge. However, it also introduces heightened security risks. Integrating legacy technology with modern software is a challenge because the different tools may be completely incompatible or create significant failure points.

Security tools may not connect properly to core systems, such as identity and access management (IAM) tools, resulting in shadow IT and poor viability.

All these milestones present challenges in maintaining cybersecurity, so you need to start by developing a formalized cybersecurity continuity plan. Let’s take a look at what to include in that plan.

What a Cybersecurity Continuity Plan Must Include

A solid cybersecurity continuity plan serves as the blueprint for maintaining resilience during incidents, organizational changes, or disasters. It ensures that security posture remains strong and operates as a robust, proactive plan that anticipates potential vulnerabilities. The plan should be thoroughly documented, formalized, and circulated to all stakeholders and leadership.

Here’s what to include in your plan:

Risk Prioritization

Prioritize your infrastructure based on business criticality, data sensitivity, and threat likelihood. Not all systems are created equal. Prioritize mission-critical assets and infrastructure that can’t fail without massively disrupting your business.

Perhaps that’s a physical manufacturing line or inventory management system that would bring your global operations to a screeching halt. Perhaps it’s a revenue-generating operation, such as a customer order portal, which would halt all new business and cash flow.

These are the highest-priority systems and may take precedence over a marketing platform or customer data repository.

Roles and Responsibilities

Detail roles and responsibilities to assess who’s accountable before a crisis occurs. Ensure each system has primary and backup owners and includes cross-functional roles like marketing and human resources (HR). Establish clear succession routes in case someone is unavailable.

Communication Plans

Clear communication during a crisis is often the deciding factor between a contained incident and a full-blown disaster. Create a strong communication plan that includes clear reporting paths to formalize how team members will communicate, and designate spokespeople in advance to speak to the media and customers.

Also, secure communication channels, especially if there is a data breach, to prevent interception by cybercriminals.

Access Control Flexibility

During transitions, it’s important to quickly adjust access controls to limit permissions, automate offboarding and prevent shadow IT. Use least privilege by default, and explore just-in-time access to grant permissions with automatic expirations.

Centralized identity and access management tools help streamline these workflows, reduce the likelihood of human error, and automate onboarding and offboarding at scale for consistency. Vet these IAM tools to understand user life cycle management capabilities, compatibility with existing infrastructure, and analytics and reporting for compliance.

Tested Playbooks

Once your cybersecurity business continuity plan is in place, don’t wait to test your strategies. Run simulations and stress test systems and measure response time, communications, and overall procedures.

Now that it’s clear what goes into a formalized, solid business continuity plan, it’s time to get all employees, stakeholders, and leadership on board, which is often the most difficult part.

Change Management and Cybersecurity

Effective change management means IT and security teams have a seat and a voice at the planning table to operate as strategic partners from day one. They can help you assess overlooked vulnerabilities, fragmented systems, and potential areas of major risk.

Change management is an art and a science that can make or break security during transitions.

Centric Consulting’s national people and change practice lead Hilary Lee writes, “Trust should be built long before challenges arise, and leaders who take intentional steps to foster it create teams that are more resilient, engaged, and prepared to navigate whatever comes next.”

Leadership-led change management offers clarity, accountability and direction.

To avoid massive business disruptions, incorporate cybersecurity checkpoints into the project timeline and ensure that IT and security teams are actively involved in major organizational changes.

Here are a few best practices for change management in cybersecurity:

• Ensure leadership remains consistent in policing policies, follows through on commitments, and maintains a clear vision even in uncertain times.
• Prioritize active listening and adjust policies as rules and regulations allow.
• Focus on being transparent about the decision-making process.

When leadership champions the change, real movement can happen even in uncertain times. But before these monumental shifts occur, spend time stress testing your cybersecurity continuity plan with real-world tactics.

Real-World Tactics to Keep Cybersecurity Continuity Intact

Real-world execution determines whether your cybersecurity continuity plan will actually work. Running proactive risk assessments, conducting quarterly tabletop simulations, or engaging external experts for fresh perspectives are a few ways to prepare and practice before an incident.

Try these real-world tactics to ensure your plan will work as intended:

Pre-Change Risk Assessments

A pre-change risk assessment helps catch vulnerabilities before they happen. It operates as an early detection system to identify gaps, assess security interdependencies, and outline potential mitigation steps and rollback plans in the event of an issue. When these are complete, security teams can sign off on the plan with confidence.

Tabletop Simulations Specific to Organizational Change

Organizational change-specific drills help identify potential weaknesses, validate plans, and let teams practice operating under pressure. For example, simulate scenarios like a disgruntled ex-employee attempting to access a system after a restructuring or a critical system failing while integrating two cloud service providers.

Role-Based Access Audits Before and After Shifts

Your access control is only as good as your last audit, so build constant reviews into your change management workflow. IAM tools help automate deprovisioning and commissioning for user groups, and a pre-shift access audit helps establish a clear baseline. It can review access, revoke potentially elevated permissions, and confirm systems are operating under tight security.

External Experts for Fresh Eyes on Overlooked Risks

External experts with fresh eyes bring a new perspective and can help identify potential biases and errors. They can also develop innovative methods to solve complex problems, enhance decision-making, and support organizational change management.

Getting feedback from knowledgeable outsiders is an indispensable part of stress testing any plan.

For example, Centric Consulting addressed these organizational pain points for a global financial company during multiple mergers and acquisitions, which were part of a rapid growth stage, by offering project leadership, partner implementations, and staff augmentation.

Stress Test Your Security Posture Before Your Next Major Change

Major organizational shifts are prime opportunities for cybercriminals. Every new leader, new technology implementation, or M&A is stress testing your security posture. Hopefully, nothing breaks.

Luckily, you can establish proactive prevention strategies and recovery plans to ensure seamless security continuity throughout periods of transition.
