Why XDR As We Know It Will Fail

Palo Alto Networks CTO Nir Zuk first coined the time period prolonged detection and response (XDR) in 2018. The idea of XDR, which Palo Alto describes as “breaking down conventional safety silos to ship detection and response throughout all knowledge sources,” is a sound one. And as cloud adoption and use of software-as-a-service apps skyrocketed within the wake of the worldwide pandemic, so has the necessity to get knowledge from all of those disparate platforms and instruments in a single place for safety investigations — therefore the hype round XDR over the previous few years.

However there is a huge distinction between a expertise’s idea and its execution, and I consider XDR — each the single-vendor strategy and the open or hybrid mannequin — has inherent limitations that may stop it from succeeding available in the market.

The Drawback With Single-Vendor XDR
Single-vendor XDR guarantees a single supplier will provide all of the out-of-the-box capabilities required to efficiently execute menace detection and response throughout knowledge silos, together with all of the accumulating, aggregating, correlating, and analyzing required for safety investigations. With as we speak’s dispersed knowledge and disparate safety instruments, nevertheless, it is unrealistic to assume that anyone vendor can have all one of the best applied sciences and capabilities required to carry out environment friendly safety investigations. However even when they do, this monolithic strategy normally entails one mega trade participant buying a bunch of smaller corporations to piecemeal collectively an entire safety portfolio. There’s little enterprise incentive to make sure all these disparate applied sciences are tightly built-in, which is a requirement for constructing a completely practical XDR platform.

Moreover, the necessity for XDR largely stems from challenges with safety data and occasion administration (SIEM) and safety analytics to help safety operations. SIEM was the unique correlation level for disparate knowledge sources. Nevertheless, SIEM guidelines and analytics capabilities shortly led to an amazing variety of alerts, and subsequently, a major variety of false positives. If SIEM — and later safety orchestration, automation, and response (SOAR) methods — could not assist us get all knowledge in a single place, with the context and data required for correct safety investigations and to make knowledgeable response choices, why do we expect XDR can? Particularly as we speak when knowledge selection and quantity make knowledge centralization inconceivable?

Final, however definitely not least, the single-vendor strategy to XDR assumes that organizations will rip and exchange their current expertise stacks that they’ve invested in over time in favor of a single XDR vendor’s platform. And one can solely think about what a CEO or board member’s response might be if a CISO or safety chief asks to scrap on a regular basis, cash, and energy put into their safety ecosystem to place all their eggs in a brand new, single basket — an XDR vendor that guarantees, however hasn’t but confirmed, that it might centralize knowledge and applied sciences for more-accurate menace detection and response.

The Drawback With Open or Hybrid XDR
On this XDR mannequin, organizations can use level options from numerous open or hybrid XDR distributors. This technique accounts for the “rip and exchange” situation, as many enterprises have already invested in lots of of those safety applied sciences, however — identical to the single-vendor strategy to XDR — right here too, there nonetheless must be a connectivity layer that integrates all these siloed instruments. And this introduces a couple of questions: Who’s chargeable for doing this? Is it real looking for us to assume that particular person distributors will seamlessly combine with one another and take away the burden from clients? Or will clients be pressured to signal on with managed detection and response (MDR) gamers to off-load the heavy lifting?

These are essential questions to guage as a result of, with out this connectivity layer, it is inconceivable to convey collectively disparate applied sciences and platforms, which suggests it is inconceivable to facilitate knowledge entry throughout all silos to assist safety analysts perceive the relationships amongst knowledge to provoke knowledgeable response actions. And this implies XDR will fail to ship on its supposed outcomes.

One extra level to contemplate: We’re beginning to see XDR alliances emerge, that are designed to beat this integration situation by connecting member applied sciences in a single ecosystem to assist analysts enhance threat-detection and response capabilities. However these teams are nonetheless closed ecosystems, limiting clients to solely the applied sciences supplied by the distributors which might be members of the required alliance. So, corporations nonetheless should rip and exchange current infrastructure and allocate time, finances, and assets to implementing these new applied sciences.

Seeing Past the Hype
Is there hope that XDR will improvise and adapt to ship on its unique promise? Probably, if XDR distributors begin to notice the significance of a connectivity layer that sits on prime of the safety ecosystem to offer entry to all the information these instruments present.

However XDR is a whole lot of hype with out the supporting longevity — and it’ll grow to be a expertise of the previous inside just some years. On the finish of the day, it is a new try at fixing the decades-old drawback of extra environment friendly safety investigations. I believe corporations will see an identical outcome to what they skilled with SIEM and SOAR applied sciences — thousands and thousands of {dollars} and years of time invested to get alert fatigue and subpar outcomes.

The takeaway right here is that corporations should not take the hype at face worth and blindly throw cash on the newest and best safety acronym. They need to do the due diligence required earlier than implementing any new safety expertise. Moreover, whether or not utilizing XDR, SIEM, SOAR, or one other expertise to assist in safety investigations, safety groups ought to think about including that integration layer. Solely then will they be capable to make the transition from utilizing a subset of their knowledge in safety investigations to accessing all of it for extra correct investigations and knowledgeable response choices.
