Layered Security That
Doesn't Slow You Down

Cybersecurity isn't about adding one tool and calling it done — it's about building layers of protection so that if one defense is tested, others are already standing behind it. At Presti & Naegele, we design and manage practical, multi-layered security programs that protect your business from the most common and most damaging threats, while recognizing that strong security should safeguard your data and your people without getting in the way of the work they need to do.


Our Approach to Layered Cybersecurity

We start with identity, because it's one of the most effective places to stop an attack before it begins. Multi-factor authentication (MFA) is implemented carefully across your organization — not just switched on and forgotten — so it actually closes the gaps it's meant to close. From there, we layer in endpoint detection and response (EDR) that actively monitors devices for suspicious behavior in real time, rather than relying on outdated antivirus signatures that only catch known threats after the fact. Patch management runs continuously in the background, because unpatched software remains one of the most common ways businesses are breached — often through vulnerabilities that have been public knowledge for months.


We also pay close attention to the human side of security, since technology alone can't stop every threat. Email and web content filtering catch a significant share of malicious traffic before it reaches your team, but employees remain your first line of defense against the threats that get through. That's why we build in security awareness training that helps people recognize phishing attempts and social engineering tactics, rather than treating training as a one-time checkbox. Behind all of this, we monitor your environment around the clock — so if something does slip past these layers, we're already responding before it has a chance to spread.

What We Manage:

  • Multi-Factor Authentication (MFA) / Two-Factor Authentication (2FA)
  • Antivirus & Endpoint Detection and Response (EDR)
  • Backups
  • Content filtering
  • Continuous patch and update management
  • Security awareness training
  • 24/7 monitoring and incident response

Why Cybersecurity Matters for Your Firm

Accounting firms are particularly attractive targets for cybercriminals, holding sensitive financial data, tax records, and client information that can be exploited or held for ransom. A single successful phishing email or unpatched vulnerability can lead to a breach that costs far more in remediation, legal exposure, and reputational damage than the cost of prevention ever would.

SCHEDULE A CONSULTATION

Beyond the financial risk, clients trust your firm with deeply personal financial information, and a security incident can erode that trust in ways that are difficult to rebuild. Layered security isn't about eliminating risk entirely — that's not realistic for any organization — but it dramatically reduces your exposure and ensures that if something does happen, it's caught early and contained quickly.

Find Out Where Your Gaps Are

Most businesses don't know their actual security posture until something goes wrong. We can help you find out before that happens. Schedule a cybersecurity assessment with Presti & Naegele to see where your current defenses stand and what it would take to close the gaps.

FREQUENTLY ASKED QUESTIONS

  • What's the difference between antivirus and endpoint detection and response (EDR)?

    Traditional antivirus works from a list of known threats, which means it tends to catch problems only after they've been identified and cataloged. Endpoint detection and response (EDR) goes further by actively monitoring devices for suspicious behavior in real time, so it can flag and respond to new or evolving attacks that signature-based antivirus would miss. We deploy and manage both as part of a layered defense, rather than relying on any single tool.



  • Why does my firm need multi-factor authentication (MFA)?

    Stolen or guessed passwords are behind a large share of breaches, and identity is one of the most effective places to stop an attack before it starts. Multi-factor authentication adds a second verification step, so a compromised password alone isn't enough to get in. We implement MFA carefully across your organization — not just switched on and forgotten — so it closes the gaps it's actually meant to close without creating friction for your team.



  • Do you provide security awareness training for our staff?

    Yes. Because employees are your first line of defense against threats that slip past technical controls, we build in security awareness training that helps your team recognize phishing attempts and social engineering tactics. We treat it as an ongoing part of your security program rather than a one-time checkbox, so awareness keeps pace with how attacks evolve.



  • What does a cybersecurity assessment involve?

    A cybersecurity assessment reviews where your current defenses stand — across identity, devices, patching, backups, filtering, and user practices — and identifies the gaps that leave you exposed. From there, we give you a clear picture of your security posture and a practical, prioritized path to closing those gaps, so you can make informed decisions before a problem forces the issue.

I have had my business for more than 10 years and struggled through several *truly awful* accountants. I found Presti & Naegele about 5 years ago and have never looked back. They are a life-changing breath of fresh air and they will be my accountants for as long as I live.

Andy and the whole Presti Naegele team have been game changers as accountants for our business. My previous accountant was very hands-off and not accessible. Andy and his team are always available, willing and able to roll up their sleeves no matter what we throw at them. Highly recommend - do NOT hesitate to work with them!
