Identity and Access Management (IAM) for Mergers and Acquisition

2021 saw an unprecedented rise in the pace of mergers and acquisitions. M&A activity saw a sharp uptake after the 2020 COVID-19 pandemic and the resulting economic recession. S&P Global Market Intelligence reported the value of M&A activity had surpassed $1 trillion by the second quarter of 2021. Another report from Refinitiv Data places the value of pending and completed deals in 2022 at a staggering $3.6 trillion, with over $2.14 trillion in the US alone. With over 35,128 deals completed in 2022, according to Refinitiv, the real impact of the M&A activity is felt after the deals close and the new organizations try to maximize the value of their merged or acquired companies amid the complexities surrounding access and resources. It’s critical to strike a balance early on between efficiency and security regarding access management.

All companies face ongoing access challenges in the increasingly complicated online environment full of malicious actors and threats. However, organizations going through M&A activity are more susceptible to access risks in the early days due to significant business changes.

This recent webinar by Agile IT CEO Conrad Aramont looked deeply into identity and access management (IAM) for M&A and the best practices for smooth sailing from the start.

What Is Identity and Access Management?

Identity and access management (IAM) refers to a framework of business policies, technologies, and processes facilitating the management of digital and electronic identities. It gives IT managers control over user access to systems and information across the organization.

IAM manages the lifecycle of user identities, access, and entitlements across enterprise resources in data centers and the cloud. It has become a foundational control of cloud security since it authenticates users and regulates their access to data, systems, and networks.

Some of the systems commonly used for IAM are single sign-on (SSO) systems, privileged access management, and multi-factor authentication. These technologies also enable organizations to securely store profile and identity data and allow efficient data governance.

Organizations can deploy IAM systems internally, outsource to a third-party vendor through cloud-based subscription models, or via hybrid models. Organizations handling sensitive customer data, like those in the financial or healthcare sectors, can enable a zero-trust strategy.

The Need for Identity and Access Management for M&As

When organizations merge or acquire other companies, one critical item to do immediately is to determine the right levels of access to grant existing employees and what they need to complete their jobs successfully.

Employees need access to multiple systems, apps, and data spanning both corporate entities. These include customer relationship management (CRM) platforms, workforce collaboration tools, human resource information systems (HRIS), accounting systems, patient care apps, banking software, and more.

Unfortunately, M&A activity rapidly enables single sign-on (SSO) access to acquired employees for business continuity. While the business needs to provide access to new users, doing it too quickly creates situations where companies grant access without considering the least privileged approach.

2021 Core Security report on identity and access management showed that 77% of organizations have users with more access privileges than necessary. It leaves such organizations vulnerable to unauthorized access to sensitive systems, data, and applications across their network, whether intentional or not.

Mergers and acquisitions come with new access and security challenges threatening normal business operations. M&A activity comes with time and operations constraints in the early days, with demands for results and shared benefits. The new organization looks to grow through acquisition and will be keen to consolidate its IT services, applications, and data to facilitate smooth operations.

Improved productivity relies on a unified experience for information, systems, and network access. However, without proper planning, risks emerge, such as identity management and miscommunication arising from misalignment of terminology.

Identity Is First

Identity always comes first because all access and services depend on identity. Organizations coming out of M&A activity must consolidate identity first before anything else. It’s a complex process considering the new size of the organization, but necessary and achievable.

These complex identity consolidation scenarios require proper planning and often impact users before achieving the required result. Still, it’s less costly than a network or system breach stemming from avoidable vulnerabilities.

Below is an example of an organization’s identity decisions post-M&A:

1. Azure Active Directory and Microsoft 365

  • Contoso tenant becomes the future home of the consolidated cloud identities
  • Contoso & Fabrikam will run on Hybrid cloud-managed  devices
  • The organization will directly join Liteware and AdventureWorks with Azure AD with Intune management

2. Local Active Directory

  • The organization will retain local AD because of time and LOB application constraints
  • It will require network connectivity between environments for other LOB, so Local AD can leverage it
  • The Fabrikam data center will handle Azure AD Connect between forests
  • Liteware will handle Azure AD Connect provisioning if there is no immediate need for hybrid device management

3. Email and Cloud File Sharing

  • Contoso tenant will house all email services and the related cloud file sharing

Define the Direction

Organizations going through M&A should define the direction early on using objectives and constraints. Objectives define what the organization intends to achieve, while the constraints impact the design and assessment options.

Objectives to include are:

  • Migration preparation: The organization identifies a plan for the identity project and offers guidance on what should change before it starts.
  • Security and compliance: These objectives guide leveraging systems and applications such as Microsoft services to strengthen the overall security posture.
  • LOB impacts and direction: Involves identifying and providing guidance on Line of Business (LOB) application impacts throughout the process

The constraints include the following:

  • Dates: Is it contractual-based with deadlines?
  • Infrastructure: Networking capacities
  • Apps: They leverage a combination of Azure active directory (AD), Local AD, and AD FS
  • User access: Access to applications and systems requires users to have local AD accounts.

Assessment and Planning

The process of assessment and planning for identity access management will look like this:

  • Learning and agreeing on common terminology to remove confusion and ensure everyone is on the same page
  • Mapping identities, including users, groups, and devices
  • Identifying naming collisions and creating explicit rules for handling them
  • Collecting and understanding the licensing landscape
  • Defining a clear and inclusive plan for the organization’s identity direction and execution
  • Understanding how the identity plan will affect users and addressing the arising issues head-on

Key Considerations and Challenges

Below are some of the expected considerations and challenges of identity and access management:

Microsoft Licensing

  • Purchasing a Microsoft Enterprise Agreement requires proper planning and consideration with the provider to ensure the timing of the license transition does not affect migrations
  • Purchasing a license via Microsoft CSP with a partner requires prior planning to ensure contracts and handoff don’t affect the migrations. It comes with a different host of problems than an enterprise agreement

Devices Changing Primary Directories

  • Joined or hybrid devices present the biggest challenges if they don’t change the Local Active Directory
  • Direct Azure AD or Intune Enrolled devices also require planning, testing, and other manual activities to migrate

Prevent Significant Identity Changes During the Migration or Transition

  • Changing user and group attributes
  • Changing to the defined pattern of rules pattern required for remediation

DNS

  • Timing of external changes, such as who has access and what should be changed
  • Transitioning custom domains between tenants can impact email routing

Service Availability

  • Understand that during a transition, there will be downtime and outages for users and devices

Documentation

  • Document everything from the start and keep updating the process
  • Ensure all teams understand the changes

The Demands of M&A Require Identity and Access Management

Organizations going through M&A can succeed by establishing sound identity and access management policies to ensure all users get appropriate access levels.

Identity is the priority because access and services rely on it. Organizations should first consolidate identity after an M&A activity. It’s a complex process that requires proper planning and execution since it will affect the entire organization.

Organizations need to collect, aggregate, and reconcile all identities spanning across all systems immediately and make it a going concern to reduce conflicts, duplications, and last-minute headaches. The last thing a company needs is a disgruntled former employee with high-level access gaining unauthorized access to sensitive data.

Next, organizations should prevent or limit changes in the identity landscape as they execute the plan based on what they assessed and defined. Before undertaking any identity planning or definition, they must start a conversation with all the relevant licensing vendors.

Automation is key to a successful, consistent, and frequent assessment and validation process.

Adapting a solid IAM approach helps bolster overall organizational risk management and achieve the ideal balance between user efficiency and organizational security.

Agile IT Can Help With Identity and Access Management for M&As

When you acquire or merge with another company, you acquire or combine its assets, including different types of hardware, software licenses, and contracts. M&A activity should bring in benefits, not financial losses. Prioritize identity and access management after an M&A to ensure smooth sailing and business continuity.
