STERLING, VA / ACCESS Newswire / July 15, 2026 / Sivadeep Katangoori spent a decade building the data platforms that corporate cybersecurity runs on. He has now built a system that carries a vulnerability from first signal to verified closure without waiting for anyone to open a ticket. His argument is not really about software. It is about what happens to an economy when its defenders move slower than the machines attacking them.

1. Executive Summary

A vulnerability disclosed on a Tuesday morning used to be somebody's problem for the rest of the quarter. Security teams triaged. Engineers scheduled. Vendors shipped a patch when they shipped it. The whole arrangement rested on a comfortable assumption: the attacker was a person, and people are slow.

That assumption has quietly expired.

Autonomous models now probe infrastructure, generate working exploits, and iterate without a human touching a keyboard. The interval between a flaw becoming known and that flaw being weaponized has compressed from weeks to hours. Corporate defense, meanwhile, still runs on ticket queues, approval chains, and change windows measured in days.

For a board, the consequence is not technical. It is a widening gap between the speed at which an organization can be attacked and the speed at which it can respond. Every day inside that gap carries a price: dwell time, regulatory exposure, insurance repricing, and the salaries of skilled people performing work no person should be performing.

Sivadeep Katangoori has spent his career at the exact seam where that gap becomes measurable. A Security Specialist and Solution Architect who built enterprise data platforms and cyber analytics systems inside two of the largest financial institutions-Bank of America and Wells Fargo, now leads vulnerability remediation and threat hunt modernization for Bank of America. The system he designed, Agentic Zero-Day Vulnerability Remediation, closes the loop between finding a flaw and proving it is gone.

The proposition invites obvious skepticism, and Katangoori does not dodge it. Nobody is proposing that machines patch a production network unsupervised. What he proposes is narrower and harder to argue with. Wherever a person currently sits waiting for context, a machine can assemble that context first. The human still decides. The human simply decides in seconds, with everything already in front of them.

How much further the machine is permitted to go is not an engineering question. It is a governance decision, and it belongs to the executive team.

2. Professional Background

Katangoori did not arrive in the security domain through a security operations center. He arrived through the infrastructure underneath it, which turns out to be the more useful door.

He began as a platform engineer at Bank of America, building the Global Information Security Data Lake and, shortly after, the cybersecurity operations analytics platform that ran on top of it. He then spent four years at Wells Fargo running enterprise data lake infrastructure, designing critical applications, and reducing infrastructure cost. A period in consulting followed, delivering data platform solutions to state agencies. In 2025 he returned to security and finance, this time as a Security Specialist and Solution Architect, with vulnerability remediation and threat hunt mitigation in his direct scope.

He came back to modernize the foundations he had helped lay, which had carried a decade of security operations and were never designed for an adversary that does not sleep.

The philosophy

One of his own article titles states it more cleanly than any paraphrase: AI strategy is not about models, it is about platforms. Models get replaced every few months. What determines whether an organization extracts value from them is the connective tissue underneath - Data Contracts, Governance, Orchestration, and audit readiness.

The problem

The gap between knowing and doing. Most enterprises are not short on detection. They are drowning in it. What they lack is the machinery to turn a detection into a defensible action fast enough to matter.

3. The Work: What Was Built

The coverage gap you are already paying for

A mature security program typically funds four categories of tooling. Each is excellent at one thing and structurally incapable of the next.

  • Vulnerability scanners find what is already catalogued.

  • Threat intelligence platforms describe what is happening in the world. They do not touch your infrastructure.

  • Automation and orchestration platforms execute workflows against indicators someone has already defined.

  • Endpoint and extended detection platforms spot unusual behavior and can quarantine a machine. Containment is not repair.

Between each of them sits a handoff, and every handoff is a person. Someone reads an alert, checks an inventory, opens a ticket, waits for approval, and schedules a change. Aggregate those handoffs and you get an enterprise response time measured in weeks, defending against an adversary measured in hours. The tools are not the problem. The seams between them are.

What the system does

Described without jargon, the platform does seven things in sequence and does them continuously. It watches. It investigates what it finds. It works out how much the finding actually matters to your specific environment rather than to the world in general. It tells the right people. It proposes a fix. It applies the fix. It proves the fix worked and closes the record.

The design decision that makes this possible is unglamorous. Katangoori treated vulnerability response not as a security incident but as a supply chain, with a common language enforced at every handoff. Systems pass structured information to one another instead of waiting for a person to retype it into the next tool. That shared language, rather than any single component, is the asset.

The control model, which is a governance decision

The platform operates in two modes, and the choice between them reflects an organization's governance appetite rather than its technical maturity.

Human in Command. The machine watches, investigates, assesses, and reports. It does not remediate. People lead; the system assists. This is the posture most regulated institutions will start in, and it delivers the majority of the time savings on its own.

Human in the Loop. The machine also proposes, executes, and verifies remediation, with an explicit approval gate at every consequential step. The system leads; people approve. Nothing irreversible happens without a named human authorizing it.

The distinction reads as procedural. It is actually the governance architecture. Speed without loss of control. Automation without loss of oversight. Intelligence without loss of accountability. An organization can adopt the first mode immediately, replay it against its own historical incidents to build an evidence base, and graduate to the second when the evidence supports it. Nothing about the design requires an act of faith.

What is different

No existing category runs the loop end to end. Scanners stop at detection. Intelligence platforms stop at notification. Orchestration stops at workflow. Endpoint tools stop at containment. This closes the circuit from discovery to verified closure, with human judgment installed where judgment is warranted and nowhere it is merely ceremonial.

4. Criticality and Industry Need

The scale

Every organization with digital infrastructure is exposed, which in practice means every industry. The critical sectors are the ones where an exploit stops being an information technology problem and becomes a public one: defense and national security, government systems, finance and banking, healthcare and medical devices, transportation and logistics, energy and utilities, manufacturing and industrial control systems, telecommunications and cloud providers.

An exploit in any of them produces the same short list of outcomes. Economic disruption. Operational shutdown. Physical safety risk. Data loss. A national security incident.

What actually limits response

Ask a security leader what slows them down and you will rarely hear that they did not know about the problem.

  • Alert volume exceeds analyst capacity, so triage becomes rationing.

  • Asset inventories drift, so nobody can answer "are we affected" with confidence.

  • Patch backlogs accumulate because change management was designed for predictable release cycles.

  • Vendor advisories arrive after exploitation has begun.

  • The talent to do this work manually does not exist in sufficient quantity, and paying more does not conjure it.

The economic inefficiency

Here the argument moves beyond security. The cost of the current model is not primarily the cost of breaches, substantial though that is. It is the cost of the standing army required to prevent them.

Skilled engineers spend their days copying identifiers between systems. Capital that could fund product development funds duplicated tooling instead. Cyber insurance repricing flows through to the balance sheets of firms that never suffered an incident. Disclosure obligations tighten across jurisdictions, and compliance cost rises whether or not posture improves alongside it. Small and mid sized enterprises, unable to fund a twenty four hour operations center, effectively opt out of adequate defense and become the soft entry into the supply chains of firms that can afford it.

That last dynamic is the one that should interest economists. Concentrated cyber risk is systemic risk. It behaves the way credit risk behaved before anyone thought to model correlation.

Why traditional methods fall short

They were built for a slower adversary. Reactive workflows assume a patch will exist. Human triage assumes volume stays within human bounds. Periodic scanning assumes the interval between scans is shorter than the interval between disclosure and exploitation. All three assumptions have failed at once.

And the asymmetry compounds. An attacker who automates gets faster with every iteration. A defender who does not, does not.

5. Impact on Industry and Economy

The figures below are modeled rather than measured. They describe what the architecture implies against published industry baselines, not results observed from a production deployment. Where independent corroboration exists, it is cited.

Speed

Katangoori models the traditional response lifecycle at twenty-one to forty-five days. In the autonomous lifecycle, assessment and reporting collapse to seconds, detection and verification run in minutes, and remediation remains bounded only by patch availability and change control.

Total modeled response time falls to four to twenty-four hours, a reduction of between 95 and 99 percent depending on where in the baseline range an organization starts.

There is external support for the direction, if not the magnitude. IBM's 2025 Cost of a Data Breach Report found that organizations making extensive use of AI and automation in security operations shortened their breach lifecycle by roughly eighty days and saved close to 1.9 million dollars per incident against organizations that did not. The global average breach lifecycle still runs 241 days.

Cost

Three lines move.

  • Labor. Investigation, correlation, ticketing, and verification stop consuming analyst hours. Analysts do not disappear. They stop doing clerical work.

  • Breach exposure. Reduced dwell time reduces expected loss, which is the number underwriters actually price.

  • Compliance. Audit-ready documentation becomes a byproduct of the workflow rather than a separate project.

Modeled cost per incident falls from a baseline of 1.8 to 4.2 million dollars down to between 150,000 and 400,000 dollars, a reduction of 78 to 96 percent across the range.

Workforce

Modeled analyst time per incident falls from 120 to 250 hours down to 10 to 25 hours, reclaiming between 95 and 240 hours each time, a reduction of 79 to 96 percent

Audit preparation falls from 40 to 80 hours down to 2 to 5, a reduction of 87 to 97 percent.

The system does not replace the security workforce. It reassigns it. Triage is the least valuable and most exhausting work a skilled analyst performs, and it is the work most responsible for attrition in a field that cannot afford attrition. Moving people from clerical correlation to threat hunting, architecture review, and adversary modeling raises the productivity of every practitioner already on the payroll. In a labor market with a persistent shortage of security professionals, output per practitioner is the only variable anyone can actually move.

Market expansion

Continuous defense has historically been affordable only to organizations that could staff around the clock. Delivered as an orchestrated platform, the same posture becomes available to mid market firms, regional banks, hospital systems, and municipal utilities. This is the economically significant point. Defense stops being a function of headcount budget.

New business models

  • Managed security providers can price on time to closure rather than tickets processed.

  • Cyber insurers gain telemetry precise enough to underwrite on posture rather than on questionnaire.

  • Software vendors can consume standardized disclosure packages, shortening their own advisory cycles.

  • Critical infrastructure operators can share a common response model across sectors.

Macroeconomic benefit

Productivity, competitiveness, and stability, in that order. Productivity, because the highest skilled workers in a scarce field stop performing tasks a machine performs better. Competitiveness, because nations whose critical infrastructure absorbs machine speed attacks without service interruption retain investment that flows away from those that do not. Stability, because cyber risk propagates through supply chains, and a defense capability that scales downward to smaller firms reduces correlation across the entire network.

There is a sustainability argument too, and it is not decorative. Unplanned outages in energy grids, transport networks, and manufacturing lines are enormously wasteful. Preventing them conserves real resources.

What senior leadership should take from this

  • Ask for mean time to verified closure, not mean time to detect. A detection your organization has not remediated is a liability you have documented.

  • Treat the choice between assisted and autonomous remediation as a governance decision with a risk appetite attached, not as a procurement decision delegated to the security team.

  • Start in the assisted mode and require an evidence base before granting the system authority to act. The productivity gain arrives long before the autonomy does.

6. Innovation and Future Outlook

A new benchmark

The metric the industry has quietly settled on is mean time to detect. This platform implies a different one: mean time to verified closure. Detection without closure is a report. The distinction is not rhetorical. It changes what a security team optimizes for, what a board asks about, and what an insurer prices.

Shaping the standard

The shared language between systems is the underrated artifact. If a common contract emerges for how a vulnerability signal moves between intelligence, orchestration, ticketing, patching, and verification, interoperability stops being a vendor negotiation. Standards create markets. This one would create a market for autonomous defense components that compose.

Katangoori frames the category as Autonomous Zero-Day Defense. Whether the name survives is beside the point. CrowdStrike, Wiz, and Palo Alto each grew by naming a category before the category existed, and each was met with the same reasonable objection: this is just a feature. Categories are what features become when the underlying constraint has changed. The constraint here has changed.

Scaling across sectors

The model is sector agnostic because the language is. Each industry substitutes its own asset inventory, its own criticality weighting, its own approval policy. The circuit does not change.

The long term economics

If autonomous defense becomes standard infrastructure rather than premium tooling, the marginal cost of adequate cybersecurity approaches the cost of the computing it runs on. Whole classes of firms currently priced out of real defense come inside the perimeter. The aggregate reduction in national cyber risk is not the sum of the individual improvements. It is greater, because attacks propagate through the weakest connected node.

The honest frontier

Two problems remain unsolved, and Katangoori names both rather than waiting for someone else to.

The first is proof. Autonomous remediation is only as trustworthy as its ability to demonstrate what it changed and show that the change worked. Verification today is a rescan. The next generation of this work belongs to formal assurance, and to governance frameworks that let a regulator audit an autonomous decision after the fact.

The second is independence. A system that consumes public vulnerability feeds and vendor advisories inherits their latency, and cannot see a flaw the world has not yet published. A system that finds an anomaly in an organization's own code and telemetry does not have that constraint. The platform already reaches into both. Closing that loop, so that an internally discovered flaw with no public identifier and no vendor advisory can still be assessed, contained, and verified on internal exposure alone, is the work that would make the platform's name literally true.

Building the autonomy was the engineering problem. Earning the authority to use it is the institutional one.

7. Closing Insight

Adversaries are attacking at machine speed. Defending at human speed is not caution. It is a decision to lose slowly. The new defense is to complement the automation with the judgement.
