Common migration pitfalls and how to avoid them

Tim Bandos, CISO at Digital Guardian, shares his top tips on avoiding some of the most common migration mistakes made by companies.

Organisations familiar with the process of migrating to a new enterprise security solution appreciate the difficulty — and time — involved in this task, but staying abreast of enterprise cybersecurity needs is a business imperative. Indeed, with just one-in-10 enterprises saying that their current security solution fully meets their needs, it’s clear that most organisations will soon be preparing to adopt a new security tool or solution.

Now is the time. Cyberattacks are predicted to cost the world US$11.4mn a minute in 2021, placing cybersecurity leaders under major pressure to protect the enterprise’s most critical assets – its data and IP. Executing a migration plan is a significant endeavour, however, and must be undertaken the right way. Failure to do so could expose the enterprise to business interruption.

How do you know it’s time to break up with your current security solution provider? Below are a few indicators you should note before you plot and execute a migration strategy.

The catalysts for change

The decision to change solution providers should not be made lightly. At the same time, you should be examining your existing partnerships to determine if they have exceeded their natural sell-by date. Are your current vendor’s solutions underperforming or outdated? Are they relying on legacy technologies? If so, that potentially puts your enterprise’s reputation, customer information and other assets at risk of breach. If your existing solution isn’t keeping pace with the rate of change or evolving threat vectors, you should move to a more comprehensive solution.

Agility is another critical trait to examine. Today’s businesses are constantly transforming,  so data security solutions that take a ‘set it and forget it’ approach are no longer viable options. If existing solutions are hampering an organisation’s ability to operate in new and agile ways, that’s an existential problem. This is before we even consider shifting regulatory compliance requirements, which force organisations to re-evaluate the strength of their existing security solutions on a constant basis.

Having determined that existing systems and solutions no longer accommodate current and future needs, organisations will need to make the leap to a new vendor or solution provider. Which means that determining who and why will be the next big challenge.

Defining the migration strategy: step 1

A quick Google search reveals an abundance of vendors, all offering security solutions to fit every organisation’s need. As a result, choosing a provider can be hard for organisations. The key is to cut through the marketing jargon and deduce if the service on offer truly suits their requirements.

Start by talking to industry peers and asking which solutions they are using. Similarly, rely on analyst guidance to obtain a detailed analysis of vendors and their solutions.

The best starting point is to spend the time to define a highly structured request for proposal (RFP) inviting leading vendors to submit formal plans. You should also assemble a cross-functional project team whose job it is to refine the broader organisational needs and assess potential vendors and evaluate their ability to deliver against these requirements.

The process of RFP preparation is critical. It should involve scoping out all requirements in collaboration with stakeholders and ensuring they align with the business strategy. Develop a scoring or weighting system that will form the foundation for decision-making — including ranking desired capabilities and requirements. As part of the selection methodology, ensure that wider holistic considerations are included in the process: will the solution be intuitive for users, how will ROI be measured, is the solution agile enough to keep up with the pace of change?

Ideally, organisations will create a shortlist of no more than three vendors and use the RFP process to scrutinise their capabilities. In the course of reviewing and scoring vendors, undertake a highly targeted proof of concept programme to ensure the selected solution will suit your environment.

Defining the migration strategy: step 2

Having selected a solution provider, you’ll then want to develop a migration plan for deployment. This begins with assessing data requirements, classification, business logic and intra dependencies defining a timeline complete with a pilot test, and then designing a network topology in preparation for deployment. As part of the transition process, set clear milestones for release management, validation, cutover, and decommission.

Don’t stop there! Having successfully executed the plan, and run elements of the migration, go the extra mile to achieve maximum ROI. This requires a post-migration strategy that incorporates frequent reviews with the solution vendor focusing on improving deployment and enhancing value.

Common pitfalls and how to avoid these

Several pitfalls can doom any change programme. The most obvious: not preparing a long term migration roadmap with accountable deliverables and a stakeholder engagement and communication plan. So too is failing to prepare a contingency plan should migration team members quit mid-project. Yet another is deploying a solution before testing it and involving in-house experts.

However, thinking long and hard about what you really need to protect will be the single most important action you can take to ensure a successful migration project. Ultimately, enterprise security is not about deploying and maintaining tools. Indeed, having a ton of market-leading tools won’t make the enterprise secure unless these are appropriately integrated with the overall security strategy. Achieving this depends on understanding how the business runs and what data and apps are vital to adding value to customers and fostering a strong risk management strategy to protect these assets.

Migrating with confidence

There’s truth in the saying ‘knowledge is power’. So taking a risk-driven approach to any new solution deployed begins with achieving a deep understanding of which data assets will be most critical to protect.

Asking the right questions of the business early on in the migration programme will help determine the depth, breadth, and level of service needed – and if the security provider in question is up to the challenge. Because, in a world where traditional security borders no longer exist, the game aims to minimise detection times by utilising the right processes and data loss prevention technologies.
