Suppose your renewal quote is higher than last year’s. Your IT lead also reports a gap: if someone misused a login to the client-document system, the firm could not easily establish who opened which files, and when. The review needs to address both the price and the missing evidence.
Financial advisers are responsible for sensitive client information, from personal details to financial records. Security monitoring should help the firm protect that information and investigate misuse.
Compare keeping your current system, adding a tool alongside it and replacing it. Use the same coverage requirements, cost assumptions and trial criteria for each option.
Define the Coverage Your Firm Needs
Before booking demonstrations, agree on what the firm needs to be able to see.
Start with a real risk. Pick an incident that would harm the firm, such as a compromised staff account used to reach client files. Ask your IT lead to list the records needed to reconstruct it: identity sign-ins, email, client-document access and activity in critical applications. Include patching records in the coverage review. Verizon’s 2026 Data Breach Investigations Report found that vulnerability exploitation was the entry point in 31% of breaches across its cross-industry dataset. The report covers incidents between November 1, 2024 and October 31, 2025. It is not a financial-services-specific figure, but it supports including unpatched systems in the assessment.
Name the job before the product. A SIEM (security information and event management system) helps teams search security records across systems and investigate suspicious activity. Application-performance monitoring addresses a different need: identifying systems that are slow or unavailable. Comparison lists can mix full SIEM replacements, investigation add-ons and performance-monitoring tools. Decide which job you need done. If investigation workload is the concern, ask for testable capabilities. Microsoft documents that Sentinel groups alerts into incidents. Test whether that grouping helps your team investigate the chosen scenario.
Build a relevant shortlist. When reviewing Splunk competitors for a shortlist, treat Strike48’s vendor-authored comparison guide as background research rather than an independent ranking. Its author lists its own platform first, so check prices and figures against each vendor’s own documentation. A shortlist of three or four relevant candidates keeps the trial manageable.
Google Security Operations documents 12 months of hot data retention in its Standard package. Elastic Security states that its detection rules are open and community-reviewed, useful if your adviser wants to inspect how alerts are generated. Exabeam positions New-Scale Analytics around behavioural baselines and risk scoring for human and non-human entities, relevant when unusual account activity is the concern. CrowdStrike states that Falcon Next-Gen SIEM can analyse third-party data without requiring other Falcon modules. Use these documented capabilities to decide what each candidate must demonstrate.
Compare the Full Cost of Ownership
The licence or subscription price does not capture every cost of running security monitoring. Ask what each proposal includes and what your firm must provide separately.
Understand the charging unit. The charging unit affects how costs change as the firm grows. Splunk lists workload pricing based on resource usage and ingest pricing based on data volume, so confirm which model your proposal uses. Microsoft lists pay-as-you-go and commitment tiers for Sentinel’s analytics tier. Google Security Operations uses credits for core data ingestion; ask what the purchased capacity covers and what happens beyond it. Some vendors do not publish prices at all and quote only after a demo. Get the proposed charging model and assumptions in writing.
Ask what the quote leaves out. Use a worksheet to identify costs outside the subscription. Ask the vendor and your IT lead to enter a figure, or a zero, for each line:
- Licence or subscription charges
- Data collection, storage and retrieval
- Implementation and setup
- Internal staff time
- Training
- Support
- Running old and new systems in parallel
- Exit and data export at the end of the contract
These are questions for every candidate, not an assumption that each vendor bills them separately.
Price the same workload. Give every candidate the same brief: data sources, required retention, expected growth and a busy period such as year-end reporting. Check inclusions before comparing totals. Google documents 12 months of hot retention in its SecOps Standard package. If another quote prices that retention separately, adjust the comparison to cover the same period and access requirements. A lower subscription price may still leave the firm with higher setup or staffing costs.
Make Vendors Prove the Fit
Use a repeatable trial to check the capabilities your firm needs. The approach below is a proposed evaluation method, not a completed test or an industry benchmark.
Use the same evidence. Prepare representative logs, with your adviser’s approval of what is safe to share. Give every candidate the compromised-account scenario from your coverage exercise. Ask whether it can connect the identity, email and document records, explain why it raised an alert and export an incident timeline that a compliance reviewer or insurer could follow.
Record the result. Agree on pass conditions before the trial starts, then record the evidence consistently for every candidate.
| Criterion | Evidence requested | Pass condition |
| Record connection | Identity, email and document records in one view | All agreed sources visible in the scenario |
| Alert explanation | Plain-language reason for the alert | Both the IT lead and the approver understand it |
| Exportable timeline | Incident timeline in a shareable format | A reviewer can follow it without the vendor present |
| Approval control | Record of the rule or approval permitting an automated action | Every action traceable to an approved rule or named approver |
Check control before automation. Before enabling agents to take actions, set clear [access controls](PASTE POST URL HERE) for sensitive records, then agree which actions need human approval and what record each action must leave. Some agentic platforms require an analyst to approve critical actions, such as isolating an endpoint, before an agent carries them out. Ask each vendor where that approval step sits and test it during the trial. Exabeam says its Nova agents automate analyst tasks; ask which tasks still need a person.
Preserve continuity. Ask how the proposal handles existing data, the work involved in moving detection rules, the period of parallel monitoring and responsibility for rollback. Supplementing the current system is an option: Exabeam documents adding its analytics and automation to an existing SIEM as an alternative to replacement. Some platforms also query logs where they already sit, in stores such as S3, Splunk and Elastic, instead of moving them to a new system. Confirm how the proposed approach would work with your records and deployment.
Conclusion
A higher renewal quote is a good prompt to review security monitoring, but price alone should not decide the outcome. The firm needs a system that can show who accessed client records, explain why an alert fired and produce evidence a compliance reviewer or insurer can follow.
Start with one realistic incident, map the records needed to reconstruct it and hold every option to the same test: keeping the current system, adding a tool alongside it or replacing it. Compare quotes on the same workload, count the costs that sit outside the subscription and let each candidate prove its claims on your own representative logs.
Before approving a change, assign responsibility for reviewing alerts, approving actions and managing rollback. Include ongoing cybersecurity training in the handover plan so staff know how to respond to the evidence the system produces.
Frequently Asked Questions
Should a financial firm replace Splunk or add a tool alongside it?
It depends on where the current system falls short. If the main issue is missing coverage or investigation workload, adding a tool alongside the existing system may close the gap without a full migration. If cost, coverage and investigation quality all fall short, replacement may be worth the effort. Compare all three options against the same coverage, cost and trial criteria before deciding.
Which records should a financial firm keep in scope for security monitoring?
Start with the records needed to reconstruct a realistic incident, such as a compromised staff account. That usually means identity sign-ins, email, client-document access and activity in critical applications. Patching records also belong in the review, since unpatched systems are a common route into a network.
How can a firm compare SIEM quotes when vendors price differently?
Give every vendor the same brief, covering data sources, required retention, expected growth and a busy period such as year-end reporting. Confirm the charging unit behind each quote, whether it is data volume, resource usage, commitment tiers or prepaid credits. Then use a worksheet to capture costs outside the subscription, including setup, staff time, training, support, parallel running and data export at exit.
What should a SIEM trial prove before the firm signs?
A useful trial shows that the platform can connect identity, email and document records in one view, explain in plain language why an alert fired and export an incident timeline that someone outside the IT team can follow. If the platform automates any actions, every action should be traceable to an approved rule or a named approver.
Is it safe to let AI agents act on security alerts?
It can be, provided the firm sets the rules first. Decide who may access sensitive records, which actions need human approval and what record each action must leave. Test those controls during the trial and ask each vendor which tasks its agents automate and which still need a person.
