🥸 This is not me.

It looks like me. It sounds like me. But it's an AI-generated avatar of me, sharing the story of acceligence from our website https://t.co/7OLJtmwZL5.

🚀 The possibilities are extraordinary.
⚠️ So are the risks.

As AI-generated video and audio become increasingly indistinguishable from reality, we can no longer assume that what we see and hear is authentic, or that we're interacting with the person we think we are.

📌 A few things worth keeping in mind:

🔍 Question the source
Consider who created and shared the content, and whether you trust its origin.

🔬 Look closely, but don't rely on appearances
Even highly convincing video and audio can be entirely synthetic.

✅ Verify before you act
Especially when requests involve urgency, money, or sensitive information, confirm through an independent, trusted channel.

I'm incredibly optimistic about what AI makes possible. But our ability to question, verify, and exercise judgment has never been more important.

🙈 🙉 Seeing and hearing are no longer believing.

☑️ AI can make an organization extraordinarily busy without necessarily making it more productive.

That may be the most important lesson for executives from Meta’s reported experience trying to dramatically reshape its workforce around AI.

In his latest Computerworld article, Evan Schuman examines what happened when ambitious expectations for AI collided with the realities of enterprise execution. The story offers three important takeaways for leaders:

1. 📊 Measure outcomes, not just AI activity.
More code, more analysis, more content, and more automated actions can look like productivity. But volume is a poor substitute for business value. Leaders need to connect AI investments to measurable improvements in revenue, cost, speed, quality, resilience, or customer experience.

2. ⚙️ Automation can create work as quickly as it eliminates it.
Every AI-generated output may require validation, security, integration, governance, maintenance, or correction. The productivity equation needs to account for the entire lifecycle of the work, not simply how quickly AI can produce it.

3. 🛠️ The opportunity is still enormous, but execution matters.
This is not an argument for slowing AI adoption. It is an argument for getting smarter about it. Organizations that establish clear outcomes, redesign workflows to leverage human and machine strengths, and scale proven use cases have an opportunity to create significantly more value than those that simply pursue automation for its own sake.

💬 As acceligence CEO Justin Greis told Computerworld:

“AI can make an organization extraordinarily busy without necessarily making it more productive. We have spent decades teaching technology leaders that lines of code, closed tickets, and launched projects are imperfect proxies for business value. AI makes that measurement problem much more acute because it can manufacture activity at machine speed.”

📌 The executive question is:

“What measurable business outcome improved because AI produced it?”

⭐ That is a much higher bar than asking how much work AI can generate. It is also where the real opportunity begins.

Very grateful to be recognized by Crain's Chicago Business as a 2026 Notable Leader in Accounting, Consulting & Law.

More than anything, this recognition has me reflecting on the people who have shaped my journey over the past 25+ years. I’ve been incredibly fortunate to work with clients, colleagues, mentors, and friends (many of whom check all of those boxes) who have trusted me, challenged me, and helped me grow along the way.

And, of course, I’m especially grateful to my family, who have always been the “why” behind the journey.

Thank you to Crain’s for the recognition, and congratulations to all of this year’s honorees. I’m proud to be included among such an amazing group of Chicago business leaders.

🎶 One of my favorite summer traditions is spending evenings at Ravinia Festival.

Looking back through some of my favorite moments from last season, I'm reminded that Ravinia is about so much more than great performances. It's about time with family and friends, unforgettable summer evenings, and connecting through the universal language of music. Looking through my photos, there are far too many memories to fit into a single post.

As we count down to Saturday's season kickoff, the anticipation feels even greater this year. The beautifully renovated Hunter Pavilion is ready to welcome audiences, the lawn is lush, and the park is buzzing with excitement. I can't wait to create more memories at one of my favorite places to spend a summer evening.

I'm also incredibly proud that acceligence is a Mainstage Sponsor for such an important, mission-driven organization. Ravinia enriches our communities, brings people together, and makes the arts accessible. Supporting that mission is deeply important to us.

If you haven't explored this year's lineup yet, I highly recommend taking a look at https://t.co/WJ5XR45EOD. Whether it's your first visit or your five hundredth, there's something special about discovering an artist you love - or a genre you've never experienced - packing a picnic, and enjoying an unforgettable evening under the stars.

🤘 Here's to another amazing season. I hope to see you there!

✨ Last night was a special evening.

I was honored to be recognized by Consulting Magazine as one of its Top Consultants for 2026, surrounded by so many colleagues and friends I’ve admired throughout my career.

As I reflected on the evening, I found myself thinking less about the recognition and more about the profession itself, a profession I fell in love with long ago. Every major technological shift forces us to rediscover our purpose, and I believe AI is doing exactly that for consulting and professional services.

For a long time, many people thought information was our product. AI is reminding us that it never was. Our greatest value has always been insight, judgment, and trust. That is the irreducible core of what we do, and it matters now more than ever.

I’m grateful to the many clients, colleagues, mentors, and friends who have placed their trust in me over the years. Thank you to the acceligence family, our Advisory Board, Executive Advisors, Consultants, Alliance Partners, and Partners, and to everyone who has made this journey so meaningful.

I’m especially grateful to my kids, who remind me every day why the work matters, not just for them, but for the generations that follow.

Thank you to everyone who has been part of the journey as we build a truly independent, AI-powered, human-centered, expertise-driven management consulting firm.

The best is yet to come! 🚀

[acceligence @acceligence]

🤖 💼 One of the most interesting developments in enterprise AI is how the professional services landscape is changing around it.

Forward-deployed engineers or "FDEs" are blurring the traditional boundaries between software vendors, consultants, and implementation partners. AI providers are moving closer to delivery. Consulting firms are moving deeper into engineering. Everyone is competing to help organizations turn AI capabilities into operational outcomes.

The question for enterprise leaders isn't whether to use outside help - most organizations will - it is whether that help leaves the organization more capable, more resilient, and more independent when the engagement is over.

acceligence CEO, Justin Greis, contributed to Computerworld's latest article examining AI vendor FDEs, vendor lock-in, capability transfer, and the evolving options organizations have for building and deploying AI at scale.

⚠️ Cyber threats target people and exploit human emotion, not just system vulnerabilities.

📱 I received an SMS phishing attempt today (one of hundreds per week) impersonating the @ILSecOfState and using urgency, fear, and legal language to drive action. This is exactly how modern social engineering works - exploit trust, create pressure, and trigger a reaction before verification.

A few Wednesday-worthy reminders:
👆 Never click links in unexpected text messages
✔️ Verify requests through official channels
🚩 Treat urgency as a red flag, not a call to action
📨 These sorts of attacks extend far beyond email

Cybersecurity is no longer just a tech issue. It’s a leadership, operational, and human-risk issue.

🚀 Big news for @acceligence today!

I’m incredibly excited to share that David Neuman has joined us as Partner and Chief Operating Officer.

David has spent more than four decades leading cybersecurity and global operations at some of the most complex organizations in the world - from commanding the Air Force’s first cyber hunting unit to securing a $60B global supply chain. He’s also been serving as Chair of our Advisory Board, helping shape the firm behind the scenes.

Now he’s jumping in full-time to help scale the firm and lead our cybersecurity practice.

We’re living through one of the most significant technology shifts of our lifetime as AI reshapes how organizations operate, compete, and defend themselves. That kind of change demands leaders who understand both the technology and the operational realities of running complex enterprises. David is exactly that kind of leader.

More importantly, he’s someone I trust deeply and genuinely enjoy working with - which matters more than any resume line.

Also, after 40 years of leadership experience, he somehow still brings more energy to meetings than the rest of us combined. I’m still trying to figure out how he does that.

Excited for what we’re building together.

👏 Welcome aboard, David.

[acceligence @acceligence]

This week's market reaction to Anthropic's Claude Code Security rollout signals something bigger than product momentum. It reflects a belief that parts of the security stack may be reordered as AI-native capabilities mature.

Strengthening code security and the SDLC is a win. Models that can reason across large codebases and surface patterns that traditional tools miss represent real progress. But expanding one layer of the stack does not eliminate the rest. EDR, IAM, threat intelligence, and data protection (a few select examples) remain foundational.

What’s changing is the operating model.

AI is decoupling security outcomes from pure headcount growth. Coverage and speed to insight can increase without linear hiring. That shift will reshape strategy, workforce expectations, and competitive dynamics across the industry.

Governance must evolve just as quickly. When foundation models become embedded in development pipelines, elements of your security posture are influenced by systems outside your direct control. The opportunity is significant. So is the responsibility.

@acceligence CEO @JustinGreis shares his perspective with Evan Schuman in @CSOonline on what this means for security leaders navigating the next phase of AI-native defense.

How are you thinking about competitive pressure, workforce evolution, and governance as AI moves deeper into the stack?

👏 Big kudos to PayPal for phasing out SMS-based MFA.

📰 I had the chance to weigh in on this in Evan Schuman's recent CSO Online piece - and he did a great job unpacking the tension between security, cost, and user friction. Appreciate the thoughtful coverage, Evan.

📱 SMS was always better than nothing. But that's a low bar.

📵 SIM swapping and SIM jacking attacks are still rising, and when your second factor is tied to a phone number that can be ported, compromised, or socially engineered, you don't have strong authentication - you have a speed bump.

🥸 And for a brand as heavily spoofed as PayPal, that risk isn't theoretical. Judging from my inbox, PayPal, Norton, and Geek Squad hold the title of the most spoofed brands in my spam folder. 🏆

🏋 The real tension has always been convenience versus security. Leaders worry about friction, security teams worry about exposure. Meanwhile, phishing-resistant options like passkeys and FIDO2 (not to mention authenticators) have been sitting there, waiting for broader adoption 🚩. And while they are not 100% perfect, they are much better than SMS!

🧐 So here's the question: are we optimizing for convenience, or for resilience? Does it have to be a choice with today's modern authentication?

🛬 Curious where others land...

❓❓❓ Is SMS-based MFA still "good enough" in your environment? ❓❓❓

🚩 Reality flag: implementation and adoption of MFA is easier said than done on legacy systems...

🤖 Agentic AI isn’t creating a new identity problem. 🔥 It’s pouring gasoline on one we never finished fixing.

Non-human identities already outnumber humans by the millions in most enterprises. Autonomous agents just turn that imbalance into a math problem no CISO can win with human-scale processes. Most identity programs assume humans request access and wait for approval. Agentic AI doesn't. That gap is where control breaks down.

We've spent years pretending we could inventory our way out of this.

😱 Spoiler: we can’t.

Visibility is partial at best, governance foundations are shaky, and agents don’t politely wait for IAM workflows to catch up. They spawn, inherit trust, and act at machine speed.

Evan Schuman does a great job reporting this important topic in @CSOonline, laying out why identity is quietly becoming the operating system of trust - and why applying human controls to machine-scale problems is a dead end.

Worth the read if you're responsible for identity, security, or explaining to leadership why "just add more process" isn’t a strategy anymore.

🔐 91% of users log in at their highest level of privilege.

That’s not a tooling gap. That’s what happens when complexity wins, and humans do what humans always do - take the easy road.

Always-on privileged access sticks around because it works…right up until it doesn't. Legacy systems, fragile integrations, and operational fear - sprinkled with a touch of process laziness - turn “temporary exceptions” into permanent risk. Multiply that by non-human identities, and things get spicy fast.

Appreciate Evan Schuman for the smart, thoughtful reporting in CSO Online and for quoting me in this piece. It's a good look at why Privileged Access Management (PAM) is heading for a real reset - not because teams are careless, but because many of our access models were never designed for the environments we’re running today.

Worth a read if you’re responsible for identity, risk, or explaining to a board why “least privilege” is harder than it sounds.

🌟 I’m super excited to welcome M.J. Vaidya as an Executive Advisor at @acceligence.

I've gotten to know M.J. as someone who's actually lived at the intersection of cybersecurity, enterprise technology, and AI - not in theory, but in the chair. At a time when technology and cyber are converging, and the line between business strategy and technology strategy has all but disappeared, M.J. has led from the front. He's been accountable for outcomes, navigated real complexity, and tackled some of the hardest trust and emerging technology challenges that global organizations face today.

One of the things I believe deeply is that leaders shouldn't have to slow down or learn the hard way when the stakes are high. Our executive advisors bring on-demand, real-world experience to help clients make better decisions faster - and M.J. embodies exactly what that looks like.

I'm grateful for his innovative approach, his battle-tested track record, and the opportunity to build great things together.

✨ When I think about what makes an outstanding Executive Advisor, I look for three things: heart, head, and hands.

♥️ HEART - strong values, sound judgment, and a genuine care for people.
🧠 HEAD - deep expertise, insight, creativity, and the executive experience to see around corners.
👐 HANDS - the ability to turn strategy into action, communicate clearly, and actually get things done.

That’s why I’m excited to welcome Michael Yadgar as an Executive Advisor at @acceligence.

Michael brings all three (plus many more)...

With three decades of board-level and executive experience, he has guided global enterprises through high-stakes transformation with operational discipline, technology foresight, and a people-first mindset.

❌ Boards don’t need more cyber metrics; they need context.

That context comes from leaders who understand the business, can articulate where risk lives, and can explain how today's strategy reshapes tomorrow's exposure and what we're going to do about it.

I recently joined Paul John Spaulding on the Cybercrime Magazine Podcast to talk about why cyber resilience has become a core leadership competency. Not a technology problem to delegate, but a governance and decision-making challenge that shows up in the boardroom long before an incident or breach occurs.

We discussed what actually differentiates organizations that handle cyber risk well:

🏭 CISOs who understand the business as deeply as they understand the threat landscape
🗜️ executive teams that practice decision-making under pressure
❓ boards that ask better questions because they’re given the right context

The short version: resilience isn't built through controls and tools alone. It's built through clarity, preparation, and leadership.

🥁 Ravinia Festival (https://t.co/LtuNbjGF10) has always been about more than the music for me.

It's walking through the park as the sun starts to dip, that unmistakable feeling that you’re exactly where you’re supposed to be. It's grabbing a scoop of Cappuccino Crunch 🍦 (IYKYK) and knowing summer has officially begun. It's singing along 🎤 to Weird Al, Charlie Puth, and James Taylor with my kids - sometimes on key, sometimes enthusiastically not - and realizing they are going to do the same with their kids.

It's reconnecting with new and old friends 🤗 week after week, often without planning it, because Ravinia has a way of pulling people together. And it's seeing firsthand the impact Ravinia has beyond the lawn and the stage ❤️ - bringing music into the lives of communities through education, outreach, and access that changes lives.

That's why I’m incredibly proud to share that @acceligence is supporting Ravinia Festival as a Mainstage Sponsor for the 2026 season.

This partnership isn't about a logo on a program. It's about standing behind a place that creates pure joy, opens doors, and reminds us that culture, community, and coming together are essential - especially now.

Big or small, support matters. If you're a company or organization looking for a way to give back, Ravinia is a wondrous place that brings magic into our lives every day.

I'm grateful for the world-class Ravinia team, excited for what's ahead, and deeply honored to support an institution that has given my family (and so many others) memories we'll carry for a lifetime. 🎶
