Unified Security Management (USM) vs SIEM

Unified Security Management (USM) vs. SIEM

Security Information and Event Management (SIEM) emerged as companies found themselves spending a lot of money on intrusion detection/prevention systems (IDS/IPS). These systems were helpful in detecting external attacks, but because of their reliance on signature-based detection, they generated a lot of false positives.

Fast-forward a decade. Today, we have many IT security teams that have invested significant time, money, and personnel to support traditional SIEM products, only for the SIEM to show little-to-no delivery on the promise of security visibility. The reasons for these shortfalls are numerous.

Though organizations may be reluctant to give up the resources they’ve sunk into SIEM products, there is a hidden cost to maintaining an under-performing product that can’t keep up with today’s threat landscape.

In other words, the entire category of SIEM is flawed in its approach, especially in the mid-market where resources are often hard to come by.
Let’s examine the specific areas that lead to these failures:

  • Poor Correlation

It is difficult to strike the right balance between correlation rules that catch all possible attacks and correlation rules that produce too many false-positive alerts.

  • Ease of Use

As stated before, SIEM solutions have been around for almost a decade. These same solutions were built to serve large enterprises that typically have substantial resources and dedicated security personnel.

  • Trending and Analytics

If correlation limitations don’t cause your solution to fail, then consumable analytics will. SIEMs often have a selection of canned reports, but lack flexible data visualization tools that can capture the rapidly changing conditions in today’s environments.

  • Cost

It is expensive. While large enterprise organizations continue to pay hefty prices for these solutions, SIEM has, in most cases, been cost-prohibitive for the mid-market customer who wants to secure their organization.

The traditional SIEM approach has not kept up with the pace of changes to the IT landscape, from the influx of new technologies on the market to the recent surge in public cloud computing. As organizational security needs continue to evolve, the traditional SIEM will fall even further behind the curve.

“What Options Does My Organization Have Besides SIEM?”

Fortunately, there is an alternative to traditional SIEM, one that overcomes the challenges that continue to limit the effectiveness of SIEM technology: AlienVault Unified Security Management (USM).

IT organizations of all shapes and sizes have embraced a unified approach to security management to reduce costs, improve security visibility, and accelerate threat detection and compliance management across their on-premises and cloud environments. They need security solutions that offer significant time-to-value returns, while improving their overall security posture.

Whether large or small, all organizations need the complete visibility the USM platform offers to:

  • Detect emerging threats across your cloud and on-premises environments.
  • Respond quickly to incidents and conduct thorough investigations.
  • Measure, manage, and report on compliance (PCI, ISO, SOX, and more).
  • Optimize your existing security investments and reduce risk.
