Solve Hard Problems.Build What Lasts.
Mid-market leaders face complex technology, security, and data challenges that most firms aren't built to handle, and most budgets can't absorb at enterprise rates. Fideseo® closes that gap.
We bring senior consultants, former CIOs, CISOs, and C-suite operators, to your toughest problems. You get the expertise of a Fortune 500 advisory firm at a cost model built for your stage.
Expert consulting. Right-sized for your business.
You need experienced guidance on technology, security, data, and strategy. Most consulting engagements are built for enterprise budgets and enterprise timelines. Fideseo® is different. Our consultants bring both proprietary technology and senior expertise, structured to fit your actual business and budget. No junior teams. No bloated timelines. Just the right people, doing the right work, scoped to your challenge.
Strategic Advisory
You have a vision. Let's make sure the strategy behind it is built to compete and built to last. We work directly with your leadership team to assess your strategy, identify real competitive advantage, and expose where AI can accelerate your goals.
- Where are our strategies most exposed to market shifts or security risk?
- Does our product roadmap reflect genuine competitive advantage?
- How can AI and senior human judgment reveal opportunities we're missing?
- Are we building for growth, or building something fragile?
Digital transformation
Technology changes fast. Organizational readiness doesn't keep up by accident. We help you assess where you are, define where you need to go, and map a realistic, sequenced path to get there.
- Do we have a digital strategy truly aligned to our business goals?
- Are we getting full value from the digital tools we've already invested in?
- Is our organization genuinely equipped for the future we're building toward?
On-demand executive leadership
Sometimes the fastest way to close a leadership gap isn't a new hire. It's the right expert, embedded now. Our consultants operate as true members of your leadership team. AI-fluent, security-aware, focused on results from day one.
- Do we have the right leadership to navigate the next 12 months?
- Are we making strategic decisions with the right expertise at the table?
- Where are the leadership gaps costing us momentum right now?
AI governance, risk & compliance
AI is moving fast. Organizations that govern it well will have a lasting advantage. We build tailored AI governance frameworks, manage cybersecurity risk, and run compliance programs, powered by proprietary technology that delivers enterprise-grade outcomes at mid-market cost.
- Are our AI initiatives compliant with current and emerging regulations?
- Do we have a governance framework our stakeholders can trust?
- What are the real risks of our current AI posture?
GRCDefense®: AI-powered cybersecurity & compliance
Most organizations manage cybersecurity and compliance across 8–12 separate tools, each with its own interface, its own data, and its own bill. GRCDefense® consolidates all of it into one AI-powered platform, built by consultants who got tired of stitching point solutions together for clients.
Every module was built to solve a real problem for a real CISO, a real board, a real audit. The result is a platform that covers the full threat surface: vulnerability management, penetration testing, SAST, threat hunting, compliance, and phishing simulation. It makes findings actionable, not just reportable.
Vulnerability management
Automated scanning across all hosts and apps. CVE tracking with severity ranking, patch status, and AI triage across every commit.
Penetration testing
8 built-in tools including CrackMapExec, Nmap, Nuclei, Hydra, and Nikto. Full ATT&CK® coverage across 315 techniques from one console.
Threat hunting & compliance
Real-time log search across 1,444 events per engagement. IOC lookup, entity timeline, and MITRE ATT&CK® heatmap, all in one workbench.
Code security & phishing
SAST scanning with GitHub integration and AI triage, plus custom phishing campaigns tracked from delivery through credential submission.
Your vendor ecosystem is a security risk. We fix that.
Most organizations don't have a clear picture of the security posture of their vendors. That gap is where breaches happen. Vendor Fidelity® is Fideseo®'s structured consulting methodology for closing it: assessing vendor risk, aligning contracts with your security strategy, hardening your posture, and finding cost savings in the process.
It's not a product. It's how our consultants work, combining senior expert judgment with GRCDefense® analysis, when vendor risk, contract strategy, and security exposure all need to be addressed together. It was recognized by the Netty Awards for its approach to reducing cybersecurity risk through rigorous vendor management.
Vendor risk assessment
Structured evaluation of your full vendor portfolio against your actual security requirements.
Contract alignment
Security and compliance obligations mapped to your contracts, with gaps identified and remediated.
Posture hardening
Reduce your attack surface at the vendor level, before an incident forces the conversation.
Cost optimization
Vendor risk work routinely surfaces redundant spend. The $3M reduction above was a real client result.
Senior expertise. Right-sized for your business.
Great technology only gets you so far. The reason most mid-market companies don't get Fortune 500-quality consulting isn't access. It's cost structure. Enterprise firms charge for teams you don't need, on timelines that serve them, not you.
Our delivery model, Resource Fidelity®, is built around a different premise: every engagement uses only senior consultants, scoped precisely to your challenge, on a fixed fee. You get the same caliber of expertise a Fortune 500 company deploys, without the overhead, the padding, or the enterprise price tag. Most engagements are up and running in 3–4 weeks.
Senior talent only
Every consultant is C-suite-caliber. No junior staff padded to inflate scope.
Right-sized scope
Engagements are scoped to your challenge, not to maximize billable hours.
Fixed fees
Capped costs, structured accountability. No billing surprises.
Embedded delivery
Our consultants work inside your team, not above it. Real partnership.
Built for organizations that play to win.
Fideseo® works across industries and ownership structures. The common thread: leaders who face real, complex challenges and need senior expertise, not a junior team or a slide deck, delivered at a cost that respects their reality.
Mid-market companies
Growing companies that face enterprise-scale challenges including technology debt, security exposure, and leadership gaps, without the budget for enterprise-scale consulting costs. Fideseo® delivers senior expertise at a cost model that fits your stage.
Non-profit organizations
Mission-driven organizations face the same technology and security challenges as for-profits, often with fewer resources and more scrutiny. Our consultants understand lean staffing, donor accountability, and board expectations. Same depth of expertise, calibrated to your mission and budget.
Private equity & portfolio companies
In PE, every day of underperformance compresses returns. We move on PE timelines, report clearly, and focus on the metrics that matter: 100-day plans, due diligence assessments, and post-close stabilization. Technology debt and cybersecurity exposure are the most fixable value destroyers we see.
Your first engagement, scoped and ready to go.
Every client relationship begins somewhere. Our focused consulting engagements deliver real insight and clear recommendations in 3–4 weeks, with a defined scope, a fixed fee, and a team that knows what it's doing.
Start with one expert
Bring in a single senior consultant to address a defined challenge, shape a strategy, or accelerate a priority initiative. We map your quick wins, flag your risks, and set you up for what comes next. Typical engagement: 1–3 months to launch.
Expand as needs grow
As your engagement deepens, additional consultants can join, each matched to the specific expertise your situation requires. All engagements include capped fees, monthly status reporting, and 30-day checkpoints.
Build lasting capability
Our goal isn't dependency. It's capability. We transfer knowledge to your team, build processes that outlast the engagement, and remain available as your trusted advisors for what comes next.
What our clients say
We reduced vendor-related cybersecurity risk AND cut commercial contract spend by $3M annually. We didn't expect both. Fideseo® delivered both.
Our payment strategy and decisions are now better tuned to the realities of a fast-changing landscape.
You listened, promised great things, and delivered. My whole organization was grateful for your leadership at a critical time.
We experienced a ransomware attack on a Sunday morning. Without the Fideseo® security expertise, the outcome would have been catastrophic. Get protected before it happens to you.

Consulting built on trust.
Fideseo® is derived from the Latin roots for faith, trust, and loyalty. Those aren't just words to us. They describe how we work and what we're accountable to.
We began in 2013 as Hershfield Consulting, a strategic advisory firm built on the conviction that mid-market companies deserve the same quality of expert guidance that Fortune 500 firms get, without the enterprise price tag or the overhead.
Over a decade of client work, we refined a delivery model that makes that possible: senior consultants who embed directly into client teams, scoped precisely to what each engagement requires. We call it Resource Fidelity®: the quality of the expertise never wavers, even as the structure flexes to fit your needs.
Today we serve for-profit, non-profit, and private equity clients across technology strategy, cybersecurity, digital transformation, data, and AI. Over 90% of our clients return after their first engagement. That's the number we're most proud of.
