SIEM Optimization for an XDR Platform

Your SIEM is only as good as the data it gets

As your attack surface expands, so does the amount of data you need to index, enrich and analyze. Can your SIEM cover it all?

Can it protect all hosts and accounts?
Will it alert you to living off the land and other attacks hiding in plain sight?
Are you getting the most out of your SIEM?

The Challenge

SIEM alone can’t protect your organization

Critical detection gaps. Siloed security data. Log coverage that's never comprehensive enough and costs that keep adding up. No wonder 44% of organizations are looking to augment their SIEM solutions. You need a reliable way to spot the signs of modern hybrid attacks in progress.

Lower costs

Vectra AI customers save 30% or more by consolidating tools, offloading use cases and reducing log volume.

How it Works

Why integrate the Vectra AI Platform with your SIEM?

Vectra AI provides the integrated signal you need to find attacks, no matter your pane of glass.

Spot the earliest signs of attacker activity

Even the most advanced SIEM technologies weren’t built to handle the tens of thousands of daily attacks you’re now up against. Vectra AI’s integrated signal automatically analyzes attacker behaviors post-compromise, so you can stop attacks in real time.

“The fact that the Vectra AI Platform had a cloud capability and an on-premises solution was critical to us. It’s now very easy for us to scale, we’re not even going to put the SIEM in our environments.”

VP of SecOps

Sporting Technology Company

Ingest only the data you need

Vectra AI sends enriched data to your SIEM — no need to pay a premium to store it. With the Vectra AI Platform to do the heavy lifting, our customers save up to 50% on annual maintenance and log retention costs.

“Now, we focus on investigations and proactive threat hunting instead of chasing down logs.”

John Shaffer

CIO, Greenhill

Expand your SOC’s capacity

Offload 50% (or more) of your SIEM use cases to the Vectra AI Platform. With certified integrations for SIEM workflows, our security AI makes analyst workloads 38x lighter.

“The Vectra AI platform doesn’t require much labor to be an effective weapon against cyberattacks.”

Daniel Luttermann

Security Team Lead, Rossman

Meet or exceed compliance requirements

Modernize your security operations center without compromising on compliance. The Vectra AI Platform supports all areas of compliance, from GDPR to NIS2. Even our AI SOC 2 Type 2 Compliance Certification is a milestone for the industry.

“Vectra AI collects and stores all this historical metadata, instead of packet payloads, to protect data privacy and support GDPR. There’s no big data infrastructure to buy, install or manage.”

FAQs

Why are so many teams losing steam in the fight against modern hybrid attacks?

Many traditional SIEM operations are being put to the test by an influx of security data, and SOC teams are feeling the pain. These scary stats from Vectra AI’s State of Threat Detection report say it all:

70% of security operations analysts admit their organization has likely been compromised and they don’t know about it yet.

97% worry they’ll miss a relevant security event because it’s buried under a flood of alerts.

67% are burned out and considering leaving their jobs — or already actively looking for a way out.

For this reason, many SOC teams are looking for cost-effective ways to get more value from their existing SIEM investments.

How can you get even more value from your SIEM?

The most common feedback we get from our customers are related to cost, complexity and time to value. (Before Vectra AI, one customer was looking at a $590,000 price tag just to develop SIEM use cases.) It takes a long time to refine playbooks — let alone implement them. With so many cyberattacks now using AI, you can’t afford not to automate your investigative workflow.

However, you’ve invested a lot in your SIEM — and you shouldn’t have to start from scratch. With Vectra AI, you won’t have to.

How will integrating with Vectra AI enhance your SIEM?

Our simple integrations let you bring AI-driven threat intelligence to any dashboard. Whether through standard syslog or via API, you can export Vectra AI's entity scoring, network metadata or log output directly into your SIEM.

Our AI-driven detections cover more than 90% of MITRE ATT&CK techniques, surfacing cyber threats immediately without tuning or custom configurations. This allows you to save time and money while focusing on a smaller set of playbooks to further protect your organization.

Which SIEM use cases can you offload?

By mapping common SIEM use cases to Vectra AI detection families, our customers save time and money while speeding up detection and response.

Replace these SIEM use cases:	With the corresponding Vectra AI detection:
- Brute force attack against Azure Portal - Successful logon customer from IP and failure from a different IIP - Microsoft Entra ID (formerly Azure AD) - Multiple authentication failures followed by a success	Brute Force
- Distributed password cracking attempt in Azure AD - Entra ID - Failed logins to one account from multiple sources - Entra ID - Failed logins to one account from single source - Entra ID - Password spray attack against Azure AD	Brute Force Attempt
Change to Trusted IP Configuration	Attempts to bypass conditional access rule in Entra ID
Cryptocurrency Mining	- Crypto mining by resource hijacking - DNS events related to mining pools
Disabled Account Attempt	Attempts to sign in to disabled accounts
Palo Alto - potential beaconing detected	HTTP/HTTPS hidden tunnel
MFA disabled for a user	MFA disabled
Entra ID - New user created and added to the built-in administrators group	Newly created admin account/admin account creation
Entra ID - High privilege role was assigned	Newly created admin account/admin account creation/Redundant access creation
Security event log cleared	M365 disabling of security tools/M365 log disabling attempt
Network DDoS detected	Outbound DoS
- Firewall - Potential local port scan detected - Palo Alto - Possible internal external port scanning	Port Scan
Azure - User was granted subscription admin access rights	Redundant access creation
- Data transfer to untrusted VPCs - Time series anomaly for data size transferred to public internet	Smash and grab
DNS - Rare high NXDomain count	Suspect domain
- Rare application consent - Azure - Granting consent to third-party application with suspicious permissions - Azure - Suspicious application consent for offline access	Suspicious application permissions
- Entra ID - User added to a privileged group - Entra ID - Account added and removed from privileged groups - Entra ID - User account added to built-in domain local or global group	Suspicious Entra ID operation
Suspicious granting of permissions to an account	Suspicious Entra ID operation/Admin account creation/newly created admin account
Suspicious powershell invocation	Suspicious remote execution
Suspicious bulk download activity	Suspicious sharing activity
Anomalous sign-on location by user account and authenticating application	Suspicious sign-on
Malformed user agent	Suspicious HTTP
DNS - tor proxies	Tor activity

Should you consider SIEM alternatives instead?

If you’re not satisfied with the current threat detection, investigation and response (TDIR) use cases within your SIEM, the Vectra AI Platform is agentless and device agnostic and can be up and running in days.

Is Vectra AI a SIEM replacement?

The choice is yours. You can integrate Vectra AI with your existing SIEM to optimize investigative workflows, or switch to our AI-driven SOC platform for extended detection and response (XDR).

What kinds of results can you expect with Vectra AI’s SIEM optimizations?

Vectra AI accelerates detections and translates results against known factors so you can respond to events faster. Our customers experience:

Coverage for more than 90% of MITRE ATT&CK techniques

Up to 50% lower annual maintenance and log retention costs

85%+ higher alert fidelity

99% faster incident response

(It takes an average of 328 days* to identify and contain data breaches resulting from compromised credentials. Vectra AI helps you detect and respond to them the day they occur.)
