Ingestion nobody decided
Sources were added one at a time, each defensible on its own. Nothing ever removed one, and the volume that results is treated as a fact of nature rather than a set of reversible decisions.
Platform expertise / Splunk
Splunk will index whatever you send it, at whatever fidelity you send it, for as long as you tell it to. Every one of those is a choice somebody made — usually quickly, often years ago, and almost never written down. Aevis makes those choices explicit and then makes them again on purpose.
Splunk is third-party software selected and licensed by the client from Splunk, a Cisco company. Aevis provides advisory, engineering, content and operational services around the client’s deployment.
Machine data layer
Sourced · shaped · retained · answeredPlatform fit
The common failure is not too little data. It is a deployment carrying years of accumulated sources at full fidelity, where the search that would answer today’s question is slow, expensive, or returns three incompatible versions of the same field.
Sources were added one at a time, each defensible on its own. Nothing ever removed one, and the volume that results is treated as a fact of nature rather than a set of reversible decisions.
Parsing was done per source by whoever onboarded it. Correlating across sources means knowing which name each one used, so cross-source searching is a specialist skill rather than a capability.
Hundreds of saved searches, most inherited, many firing into a channel nobody reads. Deleting one feels risky because nobody can say who depends on it.
Our role is to make the deployment answerable, affordable and owned in your environment — not to sell an Aevis software product.
Product landscape
We shape the engagement around the products and entitlements your organisation has licensed. Scope, capability and pricing model always depend on your licensing and deployment shape.
The index, the search language and the data model everything else on the platform rests on.
Detections, risk-based alerting and the investigation workflow a security team actually works inside.
Service-level health built from the components underneath it, where the service definition is the hard part.
Metrics, traces and real-user data for teams whose question is latency rather than log content.
Playbooks that act on a finding — worth having only where ownership and exception handling are already clear.
Forwarders, ingest processing and routing — the layer where volume and cost are actually decided.
Aevis capabilities
Engage us for a focused intervention or an end-to-end programme. We work within your licensing, data-protection and retention obligations.
What is being ingested, what it costs, what actually gets searched, and which sources have never appeared in a query anybody ran.
Parsed once, correctly, against a common model — so correlating across sources stops being a specialist skill.
Detections written against a stated threat and a stated data source, with false-positive behaviour understood before they go live.
Service health defined from the business service down, so a dashboard means something to somebody outside the platform team.
Indexer and search-head architecture, capacity, upgrades and the migration work between deployment shapes.
Running the platform, the content backlog and the cost position, or standing behind a team that does.
AI and analytics in machine data
Splunk carries machine-learning and assistive capability, and it is genuinely useful for the things statistics are good at. The line below is where its output stops being a suggestion and starts being a decision — and that line does not move.
Baselining behaviour per entity and surfacing what has moved, for an analyst to interpret against context the model does not have.
Accumulating weak signals against an entity so a notable event is raised on a pattern rather than on a single noisy rule.
Drafting SPL and summarising an investigation timeline faster, with the query and its results shown rather than hidden.
What stays human — without exception
No AI closes a finding, suppresses an alert or authorises a response action. Triage conclusions, containment decisions and the choice to retire a detection are analyst judgements made under your operating model, and remain the accountable decision of the person who made them. Generated SPL is reviewed before it is saved, because a wrong query that returns rows is more dangerous than one that errors.
How value is measured
Entitlement and data
Which machine-learning and assistive capabilities are available depends on the client’s Splunk products, version and licensing, and on what the vendor ships in that release. Indexed data is processed for the agreed operational purpose only, under the client’s data-protection and retention obligations.
Connected architecture
The most valuable architecture decision on this platform is a subtraction. Every source that earns full-fidelity indexing should have a question behind it, and the ones that do not can be filtered, routed to cheaper storage, or left where they are.
Endpoints, network, cloud, applications, identity and the third parties that also emit into your estate.
Forwarders, filtering, sampling and the routing decision that sets both cost and what remains answerable.
Indexes, sourcetypes, retention tiers, the common information model and the accelerations that make search affordable.
Detections, dashboards, service health, investigation workflow and the exports other systems depend on.
Architecture boundaryAvailable features, ingest pricing model, retention tiers and app compatibility depend on the client’s Splunk products, deployment shape and licensing. We validate entitlement and capacity assumptions before committing to a design.
Delivery model
Cost work and capability work are the same work here, and doing them separately is how a rationalisation programme accidentally removes the source somebody needed.
Establish ingest volume by source, cost attribution, retention obligations and which sources are genuinely searched.
Source-level cost and value baselineDecide what earns full-fidelity indexing, what is filtered or routed, what is archived, and the questions each decision must still answer.
Written ingest and retention policyOnboarding, normalisation, detection and service content built against that policy, with parsing documented.
Normalised sources and owned contentRun the changed pipeline alongside the current one until the searches that matter return the same answers.
Verified parity before cutoverRun the platform, the content backlog and the cost position as one governed cycle.
Governed operating cycleRetire content that produces no decisions, revisit sources against changed questions, and hold the cost position.
Smaller content estate, held cost lineUse cases
Each of these is a normal starting point rather than a programme. We map the adjacent dependencies so a local fix does not create a hidden failure elsewhere.
Ingest grew year on year and nobody can attribute it. The work is source-level attribution before any negotiation.
Detection content accumulated without retirement. Precision matters more than coverage once the queue exceeds capacity.
Per-source parsing means every cross-source question is a specialist task. Normalisation makes it an ordinary one.
A migration is the moment the accumulated decisions become visible and the only cheap moment to revisit them.
Service health built from components rather than from the business service it is meant to describe.
Retention set per index by habit rather than against the obligation and the question it serves.
Engagement shapes
Which one fits is usually a question about where accountability should sit rather than about budget.
Best forA renewal you cannot explain
A bounded assessment of ingest, cost, retention and search usage, ending in a source-level list of options with a saving and a consequence against each.
Best forOnboarding, normalisation or migration
Defined scope with acceptance criteria — onboarding, CIM conformance, detection content or a migration — handed over with the parsing documented.
Best forNo standing platform team
Aevis operates the platform, the content backlog and the cost position to an agreed cadence, with the accountability boundary set out in the service agreement.
Best forA team that should own this
We work alongside your team and hand over deliberately, with content documented and train-the-trainer where the capability should stay with you.
Designed outcomes
Baselines and targets are agreed per engagement. We do not import a vendor benchmark into your estate and call it a business case.
Share of ingest volume attributable to a named source and owner.
Indexed sources that appear in a search anybody ran, over a stated period.
Notables leading to an action, and analyst time spent per notable.
Cross-source questions answerable without specialist knowledge of parsing.
No provider can guarantee a licence saving, a detection outcome or immunity from a threat. What is contracted is the engineering, the operation and the improvement practice within an agreed scope; the organisation retains its risk decisions, its retention obligations and its commercial relationship with the vendor.
Governance
This platform degrades in one direction: more sources, more content, more cost, and no mechanism that removes any of it. These are the standing controls that supply the missing direction.
A new source is admitted against a stated question, an owner and a retention decision, rather than because somebody could send it.
Detections and dashboards carry an owner and a review date; content that produces no decisions is retired rather than muted.
Ingest and cost are reviewed monthly against attribution, so a change is noticed while it is small and reversible.
Every retention setting traces to an obligation or a question, so the platform can be defended and, where warranted, shortened.
Why Aevis
We approach Splunk as a system somebody has to run to a budget after we leave. The work is designed to survive handover, a renewal and a change of platform owner.
The most valuable recommendation on this platform is usually a subtraction, and it is worth less revenue to us than the alternative. A review that only ever adds sources is not a review.
Normalisation is unglamorous and it is what decides whether cross-source questions are ordinary or specialist. We do it properly at onboarding rather than compensating for it in every search afterwards.
The people designing your detections also work queues. Precision, false-positive cost and what an analyst can actually assess in a shift are argued about from experience.
Licences are contracted directly between you and the vendor. We hold no margin in your ingest volume, which is worth checking for in any competing proposal.
Relationship clarityAevis does not claim ownership of Splunk products and this page does not state or imply a certified partnership. Product names and trademarks belong to their respective owners.
Testimonials
Each testimonial is tied to the service it refers to, so service pages can draw the relevant one automatically.
The change we noticed first was not technical. It was that there was finally one person to call, and that person already knew the history of the problem.
They rebuilt the service catalogue around how our teams actually work rather than how the platform was shipped. Adoption stopped being an argument.
We had the security tooling before Aevis arrived. What we did not have was anybody turning what it produced into decisions.
Frequently asked questions
The useful answers depend on your deployment and licensing. These are the principles we use before an assessment establishes the exact scope.
This page makes no partnership claim. Aevis provides advisory, engineering, content and operational services around a deployment the client licenses directly from the vendor. Where a formal partner relationship is relevant to a procurement, ask us and we will answer it precisely rather than by implication.
Often, and the honest version is that we can tell you what each reduction would cost you in answerability. Filtering a source, sampling it, routing it to cheaper storage or dropping it are all available, and each closes off some questions. We present the options with the consequence attached rather than a headline saving, because a saving that removes the source your next investigation needed is not one.
Sometimes, and we will say so where the evidence points that way. But most of the cost we are shown is architectural rather than a product-price problem, and it moves with you: an estate that ingests everything at full fidelity is expensive on any platform. Establish the ingest and retention position first — it is the input to that decision either way, and it is worth having before a negotiation.
Comfortably, and usually better than running one tool for everything. Splunk is strong where the question is about log content and investigation; metrics-first questions about latency and saturation are frequently cheaper and faster elsewhere. What matters is deciding which questions live where, so the same data is not paid for twice.
Yes, against a stated threat and a stated data source, with false-positive behaviour understood before anything goes live. We will also argue for retiring content: past a certain queue depth, precision matters more than coverage, because a detection nobody has capacity to assess is not a control.
That is the co-managed shape. Parsing and content are documented as they are written, the ingest policy is yours, and train-the-trainer is available through the Corporate Training practice. A supplier whose model depends on you not holding this capability is the wrong supplier for it.
