Cybersecurity Services in Tampa
Security for Tampa Bay organizations that hold patient records, move client money, handle defense information or take card payments. Our engineers in Brooklyn watch every device around the clock, lock down Microsoft 365 sign-ins and email, train staff to spot phishing, and prove your backups restore before ransomware puts them to the test.
The short answer
NetSys protects businesses in Tampa and across Tampa Bay with managed cybersecurity: detection and response for every endpoint, identity and email protection in Microsoft 365, phishing training, vulnerability scanning, and immutable backups restored on a test schedule. Our security engineers run the service remotely from Brooklyn, NY. NetSys has no office in Florida, and day-to-day protection does not depend on anyone being in your building: a compromised laptop in Tampa can be cut off from the network remotely, at any hour. When hardware has to be handled in person, we arrange the visit in advance and put the travel in writing. Terms are month to month.

Where Tampa Bay companies are exposed
Attackers go where money and data sit, and Tampa Bay has plenty of both. Hospitals and clinics keep patient records. Banks, insurers and the smaller financial firms around them move client funds daily. Subcontractors working with the commands at MacDill Air Force Base handle defense information, and hotels, restaurants and attractions take card payments with seasonal staff coming and going. At freight and logistics companies tied to Port Tampa Bay, a single email can set a large payment in motion. The FBI's figures point the same way: in its 2025 Internet Crime Report, Florida placed third among the states for both complaints and reported losses. Most of these organizations need the same few things: someone watching every device overnight, sign-ins that a stolen password alone will not open, mail filtering that catches impersonation, staff who report a lure instead of clicking it, and backups that actually restore.
How security reaches Tampa from Brooklyn
We run the whole service from our Brooklyn office, about 1,000 miles north of Tampa, and NetSys keeps no office in Florida. Distance matters less in security than most people expect. Isolating an infected laptop, disabling a hijacked account, purging a phishing message from every inbox and restoring files from backup all happen through consoles, not in person. When something physical is involved, such as replacing a firewall or a failed device, we schedule the on-site visit in advance, scope it in the proposal and state the travel in writing. Flying nonstop from New York to Tampa International takes about three hours, so visits are planned, and a pre-configured firewall can often be shipped instead. Detection runs 24/7, emergency service can be reached at any hour, and the help desk answers from 4 a.m. to 11 p.m. Eastern, seven days a week.
Pinellas, Pasco, Polk and east Hillsborough
Security coverage extends around the bay on the same remote terms. St. Petersburg and Clearwater, in Pinellas County, mix financial services with manufacturers and medical-device makers. Wesley Chapel in Pasco County opened its third hospital in 2026, and the medical practices growing around those hospitals hold patient data that HIPAA protects. Lakeland, on I-4 in Polk County, is a distribution hub, where fake supplier invoices and changed bank details are a standing risk. Brandon, east of Tampa in Hillsborough County, is a large suburb full of small offices and shops. None of these areas falls inside the regions where we provide on-site service, all of which surround New York City, so alert response, email protection, training and backup testing run remotely there too, and any visit is scheduled ahead, as it would be for Tampa.
Payment fraud and email impersonation
For Tampa Bay businesses that move money, business email compromise deserves as much planning as ransomware. Think of freight forwarders paying carriers, title and real estate offices wiring closing funds, and finance teams processing vendor invoices. The FBI's 2025 Internet Crime Report ranks it as the second-costliest fraud type in the country, behind investment scams, and it often involves no malware at all. An account is taken over or a lookalike domain is registered, and a convincing message asks for new bank details. We work on each step: Conditional Access and multifactor sign-in against account takeover, Barracuda filtering and enforced DMARC on your own domain, monitoring for new forwarding rules and unusual sign-ins, and KnowBe4 simulations built on payment lures. We also help you set a callback rule, so a change to payment instructions is confirmed by phone at a known number before money moves.
Cybersecurity in Tampa: what NetSys delivers
Watching and containing
- ThreatDown MDR agents on each desktop, laptop and server, with alerts watched day and night
- Signals from sign-ins, mailboxes and endpoints gathered in Rapid7 InsightIDR and Microsoft Defender, with a person reviewing each alert
- A compromised device cut off from the network remotely while an engineer investigates, with no travel involved
- If an incident happens, a dated account of what occurred, prepared for owners, counsel and your cyber insurer
Sign-ins, mail and staff
- Older sign-in protocols blocked, and every Microsoft 365 login checked by Entra ID Conditional Access and multifactor prompts
- Just-in-time administrator rights through privileged identity management, removed as soon as the task is done
- Barracuda filtering in front of all mail, and your domain's DMARC, SPF and DKIM records moved to enforcement
- KnowBe4 phishing simulations and training modeled on the invoice, payroll and delivery lures that target staff
Weak spots and recovery
- Scheduled Rapid7 InsightVM vulnerability scans, with every finding tracked until someone fixes it
- Managed Cisco Meraki or Fortinet firewalls that split the network into segments, with DNS filtering that follows laptops home
- Backup copies in Datto SIRIS or Veeam that cannot be edited or erased, plus scheduled test restores with written results
- A no-cost remote external penetration test, bounded by the information we can see and the scope you approve
A 40-person engineering subcontractor handling CUI
This planning example shows how we could scope the work. It is not a claim about a customer in this market or a measured result. For published customer work, see our case studies.
A 40-person engineering and technical services subcontractor with a Westshore office, several remote staff and people who spend days at customer sites. A prime contractor has sent drawings marked CUI and asked for a CMMC Level 2 self-assessment. The Microsoft 365 tenant was never hardened, three people hold permanent global admin rights, the only malware protection is whatever came preinstalled on each laptop, and the backups sit on a storage box next to the server.
- The CUI boundary drawn around the fewest practical people, devices and storage locations, then documented
- ThreatDown MDR on every laptop and server, with Defender and Rapid7 InsightIDR signals under the same 24/7 watch
- Conditional Access and multifactor sign-in enforced, and permanent global admin roles replaced with just-in-time access
- An incident plan naming who reports to DoD within 72 hours and who holds the medium assurance certificate
- A second, immutable backup copy kept away from the server room, proven by a full test restore on record
- Each NIST SP 800-171 requirement mapped to its evidence, with open gaps tracked in a plan of action
Leadership can affirm its self-assessment knowing which evidence supports each answer, an alert at 2 a.m. reaches an engineer instead of an inbox, and ransomware would meet backups locked against change or deletion. NetSys is not a C3PAO, so the affirmation stays with the company.
Seven-location restaurant group recovers from ransomware
A seven-location BBQ restaurant group in the Southwest came to NetSys after an earlier ransomware attack had ended in a paid ransom. When attackers struck again, on a Saturday with a 7-Bitcoin demand, the group was fully restored in 4.5 hours with all of its data recovered and nothing paid. The group is not in Florida, but Tampa Bay restaurants and hotels run similar seven-day, multi-location operations where a weekend attack is just as possible, which is why we test recovery before it is needed.

Florida breach deadlines and the federal rules on top
The Florida Information Protection Act, Fla. Stat. 501.171, requires any commercial entity holding Floridians' personal information in electronic form to take reasonable measures to protect it. After a breach, affected individuals must be notified no later than 30 days after the business determines, or has reason to believe, that a breach occurred. A breach affecting 500 or more people in Florida must also be reported to the Department of Legal Affairs, the attorney general's office, within 30 days, with 15 more days available for good cause shown in writing. A vendor holding the data must alert the business within 10 days. Healthcare adds HIPAA, with a 60-day outer limit for patient notice. Defense contractors with covered defense information follow DFARS 252.204-7012: NIST SP 800-171 controls and an incident report to DoD within 72 hours. CMMC Phase II was suspended on July 13, 2026; Phase I self-assessments still apply. Applicable duties depend on the business, its data and its contracts, and your legal or compliance adviser decides which apply.
What drives the cost of security in Tampa
Ongoing security is priced per user per month, and a one-time assessment or cleanup is priced as a project. The figure depends on how many people, devices and mailboxes are covered, whether your Microsoft 365 licenses already include Business Premium security features, what evidence you need to produce for HIPAA, a cyber insurer or a NIST SP 800-171 self-assessment, and how much data the immutable backups must hold. Because the work is remote, travel rarely enters the price for a Tampa Bay company; when a visit is needed, it is quoted with its travel in writing. The external penetration test is free.
Who this fits, and who it does not
Best fit: Tampa Bay organizations that hold patient records, client funds, defense-related information or card data, with nobody on staff whose job is security, such as clinics, financial and professional offices, subcontractors, logistics firms and hospitality groups. Companies with an in-house IT person can run the service co-managed.
Not a fit if you want a product dropped in and never looked at again. We review the environment and report monthly, and new sign-in and payment-approval steps change daily habits for admins, the finance team and vendors. Formal CMMC certification requires a C3PAO, and NetSys is not one.

Cybersecurity in Tampa: FAQs
Who responds if an alert fires at 2 a.m.?
Managed detection and response watches every enrolled device 24/7. When a machine looks compromised, it can be isolated from the network remotely at any hour while our engineers investigate, and emergency service is available around the clock. For everyday requests, our help desk answers from 4 a.m. to 11 p.m. Eastern time, seven days a week, which is Tampa's time zone as well.
Can you contain a security incident in Tampa without being there?
Usually, yes. Isolating a laptop, locking a hijacked account, pulling a phishing email from every mailbox and restoring from an immutable backup are all remote tasks. NetSys has no office in Florida, and a nonstop flight from New York to Tampa International takes about three hours, so when equipment must be replaced or handled in person, we schedule the visit and state the travel in writing, or ship a pre-configured replacement.
We subcontract on work tied to MacDill. Can NetSys certify us for CMMC?
No. NetSys is not a C3PAO, and since DoD suspended CMMC Phase II on July 13, 2026, contract requirements are limited to Level 1 or Level 2 self-assessments for now. We build and document the controls behind yours: NIST SP 800-171 practices, multifactor sign-in, endpoint detection, logging and tested backups, plus an incident plan for the 72-hour reporting duty in DFARS 252.204-7012, which still applies. The affirmation remains your company's.
Which Florida privacy and breach laws apply to a company our size?
For most Tampa Bay businesses the key statute is Fla. Stat. 501.171: reasonable security, notice to affected Floridians within 30 days of determining a breach, and notice to the Department of Legal Affairs when 500 or more are affected. Florida's Digital Bill of Rights puts its main duties only on companies with over $1 billion in global revenue that also earn at least half their revenue from online ads, run a smart speaker voice assistant service, or operate an app store offering at least 250,000 apps.
How would we know our backups survive ransomware?
By testing them before an attack does. We keep copies in Datto SIRIS or Veeam storage that is immutable, meaning it cannot be altered or deleted during its retention period, and we run restores on a schedule and record what came back and how long it took. You get those results in writing. A backup that has never been restored is an assumption, and ransomware is a bad time to test it.
See what an attacker sees before they do.
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
